--- In PropertyParm, value is a SEQUENCE OF octet string.  When sent 
--- by an MGC the interpretation is as follows: 
--- empty sequence means CHOOSE 
--- one element sequence specifies value 
--- If the sublist field is not selected, a longer sequence means 
--- "choose one of the values" (i.e. value1 OR value2 OR ...) 
--- If the sublist field is selected, 
--- a sequence with more than one element encodes the value of a 
--- list-valued property (i.e. value1 AND value2 AND ...). 
--- The relation field may only be selected if the value sequence 
--- has length 1.  It indicates that the MG has to choose a value 
--- for the property. E.g. x > 3 (using the greaterThan 
--- value for relation) instructs the MG to choose any value larger 
--- than 3 for property x. 
--- The range field may only be selected if the value sequence 
--- has length 2.  It indicates that the MG has to choose a value 
--- in the range between the first octet in the value sequence and 
--- the trailing octet in the value sequence, including the 
--- boundary values. 
--- When sent by the MG, only responses to an AuditCapability request 
--- may contain multiple values, a range, or a relation field.

--- In PropertyParm, value is a SEQUENCE OF octet string.  When sent 
--- by an MGC the interpretation is as follows: 
--- empty sequence means CHOOSE 
--- one element sequence specifies value 
--- If the sublist field is not selected, a longer sequence means 
--- "choose one of the values" (i.e. value1 OR value2 OR ...) 
--- If the sublist field is selected, 
--- a sequence with more than one element encodes the value of a 
--- list-valued property (i.e. value1 AND value2 AND ...). 
--- The relation field may only be selected if the value sequence 
--- has length 1.  It indicates that the MG has to choose a value 
--- for the property. E.g. x > 3 (using the greaterThan 
--- value for relation) instructs the MG to choose any value larger 
--- than 3 for property x. 
--- The range field may only be selected if the value sequence 
--- has length 2.  It indicates that the MG has to choose a value 
--- in the range between the first octet in the value sequence and 
--- the trailing octet in the value sequence, including the 
--- boundary values. 
--- When sent by the MG, only responses to an AuditCapability request 
--- may contain multiple values, a range, or a relation field.

--- In PropertyParm, value is a SEQUENCE OF octet string.  When sent 
--- by an MGC the interpretation is as follows: 
--- empty sequence means CHOOSE 
--- one element sequence specifies value 
--- If the sublist field is not selected, a longer sequence means 
--- "choose one of the values" (i.e. value1 OR value2 OR ...) 
--- If the sublist field is selected, 
--- a sequence with more than one element encodes the value of a 
--- list-valued property (i.e. value1 AND value2 AND ...). 
--- The relation field may only be selected if the value sequence 
--- has length 1.  It indicates that the MG has to choose a value 
--- for the property. E.g. x > 3 (using the greaterThan 
--- value for relation) instructs the MG to choose any value larger 
--- than 3 for property x. 
--- The range field may only be selected if the value sequence 
--- has length 2.  It indicates that the MG has to choose a value 
--- in the range between the first octet in the value sequence and 
--- the trailing octet in the value sequence, including the 
--- boundary values. 
--- When sent by the MG, only responses to an AuditCapability request 
--- may contain multiple values, a range, or a relation field.

-%% 12.1.1	Package
-%% 
-%% Overall description of the package, specifying:
-%% 
-%% 	Package Name: only descriptive
-%% 
-%% 	PackageID: is an identifier
-%% 
-%% 	Description: is a description of the package
-%% 
-%% 	Version: 
-%% 
-%%            A new version of a package can only add additional Properties, 
-%%            Events, Signals, Statistics and new possible values for an 
-%%            existing parameter described in the original package. No 
-%%            deletions or modifications shall be allowed. A version is an 
-%%            integer in the range from 1 to 99.
-%% 
-%% 	Designed to be extended only (Optional): Yes
-%%             
-%%            This indicates that the package has been expressly designed to 
-%%            be extended by others, not to be directly referenced. For 
-%%            example, the package may not have any function on its own or be 
-%%            nonsensical on its own. The MG SHOULD NOT publish this PackageID 
-%%            when reporting packages.
-%% 
-%% 	Extends: existing package Descriptor
-%% 
-%%            A package may extend an existing package. The version of the 
-%%            original package must be specified. When a package extends 
-%%            another package it shall only add additional Properties, Events, 
-%%            Signals, Statistics and new possible values for an existing 
-%%            parameter described in the original package. An extended package 
-%%            shall not redefine or overload an identifier defined in the 
-%%            original package and packages it may have extended (multiple 
-%%            levels of extension). Hence, if package B version 1 extends 
-%%            package A version 1, version 2 of B will not be able to extend 
-%%            the A version 2 if A version 2 defines a name already in B 
-%%            version 1. If the package does not extend another package, it 
-%%            shall specify "none".
-%% 
-%% 
-%% 12.1.2	Properties
-%% 
-%% Properties defined by the package, specifying:
-%% 
-%% 	Property Name: only descriptive
-%% 
-%% 	PropertyID: is an identifier
-%% 
-%% 	Description: is a description of the function of the property
-%% 
-%% 	Type: One of:
-%% 
-%%            Boolean
-%% 
-%%            String: UTF-8 string
-%% 
-%%            Octet String: A number of octets. See Annex A and B.3 for 
-%%                          encoding
-%% 
-%%            Integer: 4 byte signed integer
-%% 
-%%            Double: 8 byte signed integer
-%% 
-%%            Character: unicode UTF-8 encoding of a single letter. 
-%%                       Could be more than one octet.
-%% 
-%%            Enumeration: one of a list of possible unique values (see 12.3)
-%% 
-%%            Sub-list: a list of several values from a list. 
-%%                      The type of sub-list SHALL also be specified. 
-%%                      The type shall be chosen from the types specified in 
-%%                      this section (with the exception of sub-list). For 
-%%                      example, Type: sub-list of enumeration. The encoding 
-%%                      of sub-lists is specified in Annexes A and B.3.
-%% 
-%% 	Possible values:
-%% 
-%%            A package MUST specify either a specific set of values or a 
-%%            description of how values are determined. A package MUST also 
-%%            specify a default value or the default behaviour when the value 
-%%            is omitted from its descriptor. For example, a package may 
-%%            specify that procedures related to the property are suspended 
-%%            when its value is omitted.
-%% 
-%% 	Default:
-%% 
-%%            A default value (but not procedures) may be specified as 
-%%            provisionable.
-%% 
-%% 	Defined in:
-%% 
-%%            Which H.248.1 descriptor the property is defined in. 
-%%            LocalControl is for stream-dependent properties. 
-%%            TerminationState is for stream-independent properties. 
-%%            ContextAttribute is for properties that affect the context as 
-%%            a whole, i.e., mixing properties. These are expected to be the 
-%%            most common cases, but it is possible for properties to be 
-%%            defined in other descriptors. Context properties MUST be defined 
-%%            in the ContextAttribute descriptor.
-%% 
-%% 	Characteristics: Read/Write or both, and (optionally), global: 
-%% 
-%%            Indicates whether a property is read-only, or read-write, and 
-%%            if it is global. If Global is omitted, the property is not 
-%%            global. If a property is declared as global, the value of the 
-%%            property is shared by all Terminations realizing the package.  
-%%            If a context property is declared as global, the property is 
-%%            shared by all contexts realizing the package.
-%% 
-%% 
-%% 12.1.3	Events
-%% 
-%% Events defined by the package, specifying:
-%% 
-%% 	Event name: only descriptive
-%% 
-%% 	EventID: is an identifier
-%% 
-%% 	Description: a description of the function of the event
-%% 
-%% 	EventsDescriptor Parameters: 
-%% 
-%%            Parameters used by the MGC to configure the event, and found in 
-%%            the EventsDescriptor. See 12.2. If there are no parameters for 
-%%            the Events Descriptor, then "none" shall be specified.
-%% 
-%% 	ObservedEventsDescriptor Parameters: 
-%% 
-%%            Parameters returned to the MGC in Notify requests and in replies 
-%%            to command requests from the MGC that audit 
-%%            ObservedEventsDescriptor, and found in the 
-%%            ObservedEventsDescriptor. See 12.2. If there are no parameters 
-%%            for the ObservedEvents Descriptor, then 'none' shall be specified.
-%% 
-%% 
-%% 12.1.4	Signals
-%% 
-%% Signals defined by the package, specifying:
-%% 
-%% 	Signal Name: only descriptive
-%% 
-%% 	SignalID: is an identifier. SignalID is used in a SignalsDescriptor
-%% 
-%% 	Description: a description of the function of the signal
-%% 
-%% 	SignalType: one of:
-%% 
-%%            OO (On/Off) 
-%% 
-%%            TO (TimeOut)
-%% 
-%%            BR (Brief)
-%% 
-%% 	   NOTE - SignalType may be defined such that it is dependent on
-%%            the value of one or more parameters. The package MUST specify a 
-%%            default signal type. If the default type is TO, the package MUST 
-%%            specify a default duration which may be provisioned. A default 
-%%            duration is meaningless for BR. 
-%% 
-%% 	Duration: in hundredths of seconds
-%% 
-%% 	Additional Parameters: see 12.2
-%% 
-%% 
-%% 12.1.5	Statistics
-%% 
-%% Statistics defined by the package, specifying:
-%% 
-%% 	Statistic name: only descriptive
-%% 
-%% 	StatisticID: is an identifier
-%% 
-%% 	StatisticID is used in a StatisticsDescriptor
-%% 
-%% 	Description: a description of the statistic
-%% 
-%% 	Type: One of:
-%% 
-%% 	   Boolean
-%% 
-%%            String: UTF-8 string
-%% 
-%%            Octet String: A number of octets.  
-%%                          See Annex A and Annex B.3 for encoding
-%% 
-%%            Integer: 4 byte signed integer
-%% 
-%%            Double: 8 byte signed integer
-%% 
-%%            Character: Unicode UTF-8 encoding of a single letter. 
-%%                       Could be more than one octet.
-%% 
-%%            Enumeration: One of a list of possible unique values (See 12.3)
-%% 
-%%            Sub-list: A list of several values from a list. 
-%%                      The type of sub-list SHALL also be specified.  
-%%                      The type shall be chosen from the types specified in 
-%%                      this section (with the exception of sub-list). 
-%%                      For example, Type: sub-list of enumeration.  
-%%                      The encoding of sub-lists is specified in Annexes A 
-%%                      and B.3.
-%% 
-%% 	Possible Values:
-%% 
-%%            A package must indicate the unit of measure, e.g. milliseconds, 
-%%            packets, either here or along with the type above, as well as 
-%%            indicating any restriction on the range.
-%% 
-%% 	Level: Specify if the statistic can be kept at the Termination 
-%%                level, Stream level or Either.
-%% 
-%% 
-%% 12.1.6	Error Codes
-%% 
-%% If the package does not define any error codes, this section may be omitted.  
-%% Otherwise, it describes error codes defined by the package, specifying:
-%% 
-%% 	Error Code #: The error code number.
-%% 
-%% 	Name: Name of the error
-%% 
-%% 	Definition: A description of the error code.
-%% 
-%% 	Error Text in the Error Descriptor:
-%% 
-%%            A description of what text to return in the Error Descriptor.
-%% 
-%% 	Comment: Any further comments on the use of the error code.
-%% 
-%% 
-%% 12.1.7	Procedures
-%% 
-%% Additional guidance on the use of the package.
-%% 
-%% 
-%% 12.2	Guidelines to defining parameters to events and signals

-%%         Parameter Name: only descriptive
-%% 
-%%         ParameterID: is an identifier. The textual ParameterID of 
-%%         parameters to Events and Signals shall not start with "EPA" and 
-%%         "SPA", respectively. The textual ParameterID shall also not be 
-%%         "ST", "Stream", "SY", "SignalType", "DR", "Duration", "NC", 
-%%         "NotifyCompletion", "KA", "KeepActive", "EB", "Embed", "DM", 
-%%         "DigitMap", "DI", "Direction", "RQ" or "RequestID".
-%% 
-%%         Description: a description of the function of the parameter.
-%% 
-%%         Type: One of:
-%% 
-%%            Boolean

-%%            String: UTF-8 octet string
-%% 
-%%            Octet String: A number of octets. See Annex A and B.3 for

-%%            Character: Unicode UTF-8 encoding of a single letter. Could be 
-%%                       more than one octet.
-%% 
-%%            Enumeration: one of a list of possible unique values (see 12.3)
-%% 
-%%            Sub-list: a list of several values from a list (not supported 
-%%                      for statistics). The type of sub-list SHALL also be 
-%%                      specified The type shall be chosen from the types 
-%%                      specified in this section (with the exception of 
-%%                      sub-list). For example, Type: sub-list of enumeration. 
-%%                      The encoding of sub-lists is specified in Annex A 
-%%                      and B.3.
-%% 
-%%            Optional: Yes/No
-%% 
-%%               Describes if the parameter may be omitted from the signal or 
-%%               event.
-%% 
-%%            Possible values:
-%% 
-%%               A package MUST specify either a specific set of values or a

-%% Name:    dd - DTMF detection Package
-%% Version: 1
-%% Extends: tonedet version 1
-%% Purpose: This package defines the basic DTMF tones detection.
-%%          Tones are selected by name (tone id). MGs are expected
-%%          to be provisioned with the characteristics of appropriate
-%%          tones for the country in which the MG is located.
-%%          
-%%          This package does not specify parameter values.
-%%          It is intended to be extendable.
-%% 
-%% Additional tone id values are all tone ids described in package dg
-%% (basic DTMF generator package).
-%% 
-%% The following table maps DTMF events to digit map symbols as described
-%% in section 7.1.14.

-%% Name:  native -  Pseudo package  
-%% Version: 1
-%% Extends: None
-%% Purpose: Native tags for media stream properties
-%%
-%% Parameters for Local descriptors and Remote descriptors are
-%% specified as tag-value pairs if binary encoding is used for the
-%% protocol.  This annex contains the property names (PropertyID), the
-%% tags (Property Tag), type of the property (Type) and the values
-%% (Value).Values presented in the Value field when the field contains
-%% references shall be regarded as "information". The reference
-%% contains the normative values.  If a value field does not contain a
-%% reference then the values in that field can be considered as
-%% "normative".
-%% 
-%% Tags are given as hexadecimal numbers in this annex. When setting
-%% the value of a property, a MGC may underspecify the value according
-%% to one of the mechanisms specified in section 7.1.1.
-%% 
-%% For type "enumeration" the value is represented by the value in brack-
-%% ets, e.g., Send(0), Receive(1).

-%% 12.1.1	Package
-%% 
-%% Overall description of the package, specifying:
-%% 
-%% 	Package Name: only descriptive
-%% 
-%% 	PackageID: is an identifier
-%% 
-%% 	Description: is a description of the package
-%% 
-%% 	Version: 
-%% 
-%%            A new version of a package can only add additional Properties, 
-%%            Events, Signals, Statistics and new possible values for an 
-%%            existing parameter described in the original package. No 
-%%            deletions or modifications shall be allowed. A version is an 
-%%            integer in the range from 1 to 99.
-%% 
-%% 	Designed to be extended only (Optional): Yes
-%%             
-%%            This indicates that the package has been expressly designed to 
-%%            be extended by others, not to be directly referenced. For 
-%%            example, the package may not have any function on its own or be 
-%%            nonsensical on its own. The MG SHOULD NOT publish this PackageID 
-%%            when reporting packages.
-%% 
-%% 	Extends: existing package Descriptor
-%% 
-%%            A package may extend an existing package. The version of the 
-%%            original package must be specified. When a package extends 
-%%            another package it shall only add additional Properties, Events, 
-%%            Signals, Statistics and new possible values for an existing 
-%%            parameter described in the original package. An extended package 
-%%            shall not redefine or overload an identifier defined in the 
-%%            original package and packages it may have extended (multiple 
-%%            levels of extension). Hence, if package B version 1 extends 
-%%            package A version 1, version 2 of B will not be able to extend 
-%%            the A version 2 if A version 2 defines a name already in B 
-%%            version 1. If the package does not extend another package, it 
-%%            shall specify "none".
-%% 
-%% 
-%% 12.1.2	Properties
-%% 
-%% Properties defined by the package, specifying:
-%% 
-%% 	Property Name: only descriptive
-%% 
-%% 	PropertyID: is an identifier
-%% 
-%% 	Description: is a description of the function of the property
-%% 
-%% 	Type: One of:
-%% 
-%%            Boolean
-%% 
-%%            String: UTF-8 string
-%% 
-%%            Octet String: A number of octets. See Annex A and B.3 for 
-%%                          encoding
-%% 
-%%            Integer: 4 byte signed integer
-%% 
-%%            Double: 8 byte signed integer
-%% 
-%%            Character: unicode UTF-8 encoding of a single letter. 
-%%                       Could be more than one octet.
-%% 
-%%            Enumeration: one of a list of possible unique values (see 12.3)
-%% 
-%%            Sub-list: a list of several values from a list. 
-%%                      The type of sub-list SHALL also be specified. 
-%%                      The type shall be chosen from the types specified in 
-%%                      this section (with the exception of sub-list). For 
-%%                      example, Type: sub-list of enumeration. The encoding 
-%%                      of sub-lists is specified in Annexes A and B.3.
-%% 
-%% 	Possible values:
-%% 
-%%            A package MUST specify either a specific set of values or a 
-%%            description of how values are determined. A package MUST also 
-%%            specify a default value or the default behaviour when the value 
-%%            is omitted from its descriptor. For example, a package may 
-%%            specify that procedures related to the property are suspended 
-%%            when its value is omitted.
-%% 
-%% 	Default:
-%% 
-%%            A default value (but not procedures) may be specified as 
-%%            provisionable.
-%% 
-%% 	Defined in:
-%% 
-%%            Which H.248.1 descriptor the property is defined in. 
-%%            LocalControl is for stream-dependent properties. 
-%%            TerminationState is for stream-independent properties. 
-%%            ContextAttribute is for properties that affect the context as 
-%%            a whole, i.e., mixing properties. These are expected to be the 
-%%            most common cases, but it is possible for properties to be 
-%%            defined in other descriptors. Context properties MUST be defined 
-%%            in the ContextAttribute descriptor.
-%% 
-%% 	Characteristics: Read/Write or both, and (optionally), global: 
-%% 
-%%            Indicates whether a property is read-only, or read-write, and 
-%%            if it is global. If Global is omitted, the property is not 
-%%            global. If a property is declared as global, the value of the 
-%%            property is shared by all Terminations realizing the package.  
-%%            If a context property is declared as global, the property is 
-%%            shared by all contexts realizing the package.
-%% 
-%% 
-%% 12.1.3	Events
-%% 
-%% Events defined by the package, specifying:
-%% 
-%% 	Event name: only descriptive
-%% 
-%% 	EventID: is an identifier
-%% 
-%% 	Description: a description of the function of the event
-%% 
-%% 	EventsDescriptor Parameters: 
-%% 
-%%            Parameters used by the MGC to configure the event, and found in 
-%%            the EventsDescriptor. See 12.2. If there are no parameters for 
-%%            the Events Descriptor, then "none" shall be specified.
-%% 
-%% 	ObservedEventsDescriptor Parameters: 
-%% 
-%%            Parameters returned to the MGC in Notify requests and in replies 
-%%            to command requests from the MGC that audit 
-%%            ObservedEventsDescriptor, and found in the 
-%%            ObservedEventsDescriptor. See 12.2. If there are no parameters 
-%%            for the ObservedEvents Descriptor, then 'none' shall be specified.
-%% 
-%% 
-%% 12.1.4	Signals
-%% 
-%% Signals defined by the package, specifying:
-%% 
-%% 	Signal Name: only descriptive
-%% 
-%% 	SignalID: is an identifier. SignalID is used in a SignalsDescriptor
-%% 
-%% 	Description: a description of the function of the signal
-%% 
-%% 	SignalType: one of:
-%% 
-%%            OO (On/Off) 
-%% 
-%%            TO (TimeOut)
-%% 
-%%            BR (Brief)
-%% 
-%% 	   NOTE - SignalType may be defined such that it is dependent on
-%%            the value of one or more parameters. The package MUST specify a 
-%%            default signal type. If the default type is TO, the package MUST 
-%%            specify a default duration which may be provisioned. A default 
-%%            duration is meaningless for BR. 
-%% 
-%% 	Duration: in hundredths of seconds
-%% 
-%% 	Additional Parameters: see 12.2
-%% 
-%% 
-%% 12.1.5	Statistics
-%% 
-%% Statistics defined by the package, specifying:
-%% 
-%% 	Statistic name: only descriptive
-%% 
-%% 	StatisticID: is an identifier
-%% 
-%% 	StatisticID is used in a StatisticsDescriptor
-%% 
-%% 	Description: a description of the statistic
-%% 
-%% 	Type: One of:
-%% 
-%% 	   Boolean
-%% 
-%%            String: UTF-8 string
-%% 
-%%            Octet String: A number of octets.  
-%%                          See Annex A and Annex B.3 for encoding
-%% 
-%%            Integer: 4 byte signed integer
-%% 
-%%            Double: 8 byte signed integer
-%% 
-%%            Character: Unicode UTF-8 encoding of a single letter. 
-%%                       Could be more than one octet.
-%% 
-%%            Enumeration: One of a list of possible unique values (See 12.3)
-%% 
-%%            Sub-list: A list of several values from a list. 
-%%                      The type of sub-list SHALL also be specified.  
-%%                      The type shall be chosen from the types specified in 
-%%                      this section (with the exception of sub-list). 
-%%                      For example, Type: sub-list of enumeration.  
-%%                      The encoding of sub-lists is specified in Annexes A 
-%%                      and B.3.
-%% 
-%% 	Possible Values:
-%% 
-%%            A package must indicate the unit of measure, e.g. milliseconds, 
-%%            packets, either here or along with the type above, as well as 
-%%            indicating any restriction on the range.
-%% 
-%% 	Level: Specify if the statistic can be kept at the Termination 
-%%                level, Stream level or Either.
-%% 
-%% 
-%% 12.1.6	Error Codes
-%% 
-%% If the package does not define any error codes, this section may be omitted.  
-%% Otherwise, it describes error codes defined by the package, specifying:
-%% 
-%% 	Error Code #: The error code number.
-%% 
-%% 	Name: Name of the error
-%% 
-%% 	Definition: A description of the error code.
-%%

-%% 
-%%            A description of what text to return in the Error Descriptor.
-%% 
-%% 	Comment: Any further comments on the use of the error code.
-%% 
-%% 
-%% 12.1.7	Procedures
-%% 
-%% Additional guidance on the use of the package.
-%% 
-%% 
-%% 12.2	Guidelines to defining parameters to events and signals

-%%         Parameter Name: only descriptive
-%% 
-%%         ParameterID: is an identifier. The textual ParameterID of 
-%%         parameters to Events and Signals shall not start with "EPA" and

-%% Name:    tonegen - Tone Generator Package
-%% Version: 2
-%% Extends: None
-%% Purpose: This package defines signals to generate audio tones.
-%%          This package does not specify parameter values. It is
-%%          intended to be extendable. Generally, tones are defined
-%%          as an individual signal with a parameter, ind,
-%%          representing "interdigit" time delay, and a tone id to

-%% Name:  native -  Pseudo package  
-%% Version: 1
-%% Extends: None
-%% Purpose: Native tags for media stream properties
-%%
-%% Parameters for Local descriptors and Remote descriptors are
-%% specified as tag-value pairs if binary encoding is used for the
-%% protocol.  This annex contains the property names (PropertyID), the
-%% tags (Property Tag), type of the property (Type) and the values
-%% (Value).Values presented in the Value field when the field contains
-%% references shall be regarded as "information". The reference
-%% contains the normative values.  If a value field does not contain a
-%% reference then the values in that field can be considered as
-%% "normative".
-%% 
-%% Tags are given as hexadecimal numbers in this annex. When setting
-%% the value of a property, a MGC may underspecify the value according
-%% to one of the mechanisms specified in section 7.1.1.
-%% 
-%% For type "enumeration" the value is represented by the value in brack-
-%% ets, e.g., Send(0), Receive(1).

-%% 12.1.1	Package
-%% 
-%% Overall description of the package, specifying:
-%% 
-%% 	Package Name: only descriptive
-%% 
-%% 	PackageID: is an identifier
-%% 
-%% 	Description: is a description of the package
-%% 
-%% 	Version: 
-%% 
-%%            A new version of a package can only add additional Properties, 
-%%            Events, Signals, Statistics and new possible values for an 
-%%            existing parameter described in the original package. No 
-%%            deletions or modifications shall be allowed. A version is an 
-%%            integer in the range from 1 to 99.
-%% 
-%% 	Designed to be extended only (Optional): Yes
-%%             
-%%            This indicates that the package has been expressly designed to 
-%%            be extended by others, not to be directly referenced. For 
-%%            example, the package may not have any function on its own or be 
-%%            nonsensical on its own. The MG SHOULD NOT publish this PackageID 
-%%            when reporting packages.
-%% 
-%% 	Extends: existing package Descriptor
-%% 
-%%            A package may extend an existing package. The version of the 
-%%            original package must be specified. When a package extends 
-%%            another package it shall only add additional Properties, Events, 
-%%            Signals, Statistics and new possible values for an existing 
-%%            parameter described in the original package. An extended package 
-%%            shall not redefine or overload an identifier defined in the 
-%%            original package and packages it may have extended (multiple 
-%%            levels of extension). Hence, if package B version 1 extends 
-%%            package A version 1, version 2 of B will not be able to extend 
-%%            the A version 2 if A version 2 defines a name already in B 
-%%            version 1. If the package does not extend another package, it 
-%%            shall specify "none".
-%% 
-%% 
-%% 12.1.2	Properties
-%% 
-%% Properties defined by the package, specifying:
-%% 
-%% 	Property Name: only descriptive
-%% 
-%% 	PropertyID: is an identifier
-%% 
-%% 	Description: is a description of the function of the property
-%% 
-%% 	Type: One of:
-%% 
-%%            Boolean
-%% 
-%%            String: UTF-8 string
-%% 
-%%            Octet String: A number of octets. See Annex A and B.3 for 
-%%                          encoding
-%% 
-%%            Integer: 4 byte signed integer
-%% 
-%%            Double: 8 byte signed integer
-%% 
-%%            Character: unicode UTF-8 encoding of a single letter. 
-%%                       Could be more than one octet.
-%% 
-%%            Enumeration: one of a list of possible unique values (see 12.3)
-%% 
-%%            Sub-list: a list of several values from a list. 
-%%                      The type of sub-list SHALL also be specified. 
-%%                      The type shall be chosen from the types specified in 
-%%                      this section (with the exception of sub-list). For 
-%%                      example, Type: sub-list of enumeration. The encoding 
-%%                      of sub-lists is specified in Annexes A and B.3.
-%% 
-%% 	Possible values:
-%% 
-%%            A package MUST specify either a specific set of values or a 
-%%            description of how values are determined. A package MUST also 
-%%            specify a default value or the default behaviour when the value 
-%%            is omitted from its descriptor. For example, a package may 
-%%            specify that procedures related to the property are suspended 
-%%            when its value is omitted.
-%% 
-%% 	Default:
-%% 
-%%            A default value (but not procedures) may be specified as 
-%%            provisionable.
-%% 
-%% 	Defined in:
-%% 
-%%            Which H.248.1 descriptor the property is defined in. 
-%%            LocalControl is for stream-dependent properties. 
-%%            TerminationState is for stream-independent properties. 
-%%            ContextAttribute is for properties that affect the context as 
-%%            a whole, i.e., mixing properties. These are expected to be the 
-%%            most common cases, but it is possible for properties to be 
-%%            defined in other descriptors. Context properties MUST be defined 
-%%            in the ContextAttribute descriptor.
-%% 
-%% 	Characteristics: Read/Write or both, and (optionally), global: 
-%% 
-%%            Indicates whether a property is read-only, or read-write, and 
-%%            if it is global. If Global is omitted, the property is not 
-%%            global. If a property is declared as global, the value of the 
-%%            property is shared by all Terminations realizing the package.  
-%%            If a context property is declared as global, the property is 
-%%            shared by all contexts realizing the package.
-%% 
-%% 
-%% 12.1.3	Events
-%% 
-%% Events defined by the package, specifying:
-%% 
-%% 	Event name: only descriptive
-%% 
-%% 	EventID: is an identifier
-%% 
-%% 	Description: a description of the function of the event
-%% 
-%% 	EventsDescriptor Parameters: 
-%% 
-%%            Parameters used by the MGC to configure the event, and found in 
-%%            the EventsDescriptor. See 12.2. If there are no parameters for 
-%%            the Events Descriptor, then "none" shall be specified.
-%% 
-%% 	ObservedEventsDescriptor Parameters: 
-%% 
-%%            Parameters returned to the MGC in Notify requests and in replies 
-%%            to command requests from the MGC that audit 
-%%            ObservedEventsDescriptor, and found in the 
-%%            ObservedEventsDescriptor. See 12.2. If there are no parameters 
-%%            for the ObservedEvents Descriptor, then 'none' shall be specified.
-%% 
-%% 
-%% 12.1.4	Signals
-%% 
-%% Signals defined by the package, specifying:
-%% 
-%% 	Signal Name: only descriptive
-%% 
-%% 	SignalID: is an identifier. SignalID is used in a SignalsDescriptor
-%% 
-%% 	Description: a description of the function of the signal
-%% 
-%% 	SignalType: one of:
-%% 
-%%            OO (On/Off) 
-%% 
-%%            TO (TimeOut)
-%% 
-%%            BR (Brief)
-%% 
-%% 	   NOTE - SignalType may be defined such that it is dependent on
-%%            the value of one or more parameters. The package MUST specify a 
-%%            default signal type. If the default type is TO, the package MUST 
-%%            specify a default duration which may be provisioned. A default 
-%%            duration is meaningless for BR. 
-%% 
-%% 	Duration: in hundredths of seconds
-%% 
-%% 	Additional Parameters: see 12.2
-%% 
-%% 
-%% 12.1.5	Statistics
-%% 
-%% Statistics defined by the package, specifying:

-%% 
-%%         Parameter Name: only descriptive
-%% 
-%%         ParameterID: is an identifier. The textual ParameterID of 
-%%         parameters to Events and Signals shall not start with "EPA" and 
-%%         "SPA", respectively. The textual ParameterID shall also not be 
-%%         "ST", "Stream", "SY", "SignalType", "DR", "Duration", "NC", 
-%%         "NotifyCompletion", "KA", "KeepActive", "EB", "Embed", "DM", 
-%%         "DigitMap", "DI", "Direction", "RQ" or "RequestID".
-%% 
-%%         Description: a description of the function of the parameter.
-%% 
-%%         Type: One of:
-%% 
-%%            Boolean
-%% 
-%%            String: UTF-8 octet string
-%% 
-%%            Octet String: A number of octets. See Annex A and B.3 for 
-%%                          encoding
-%% 
-%%            Integer: 4-octet signed integer
-%% 
-%%            Double: 8-octet signed integer
-%% 
-%%            Character: Unicode UTF-8 encoding of a single letter. Could be 
-%%                       more than one octet.
-%% 
-%%            Enumeration: one of a list of possible unique values (see 12.3)
-%% 
-%%            Sub-list: a list of several values from a list (not supported 
-%%                      for statistics). The type of sub-list SHALL also be 
-%%                      specified The type shall be chosen from the types 
-%%                      specified in this section (with the exception of 
-%%                      sub-list). For example, Type: sub-list of enumeration. 
-%%                      The encoding of sub-lists is specified in Annex A

-%% 
-%%            Optional: Yes/No
-%% 
-%%               Describes if the parameter may be omitted from the signal or 
-%%               event.
-%% 
-%%            Possible values:
-%% 
-%%               A package MUST specify either a specific set of values or a 
-%%               description of how values are determined. A package MUST 
-%%               also specify a default value or the default behavior when the 
-%%               value is omitted from its descriptor. For example, a package 
-%%               may specify that procedures related to the parameter are 
-%%               suspended when its value is omitted.
-%% 
-%%            Default:
-%% 
-%%               A default value (but not procedures) may be specified as 
-%%               provisionable.
-%% 
-%% 
-%% 12.3	Lists
-%% 
-%% Possible values for parameters include enumerations. Enumerations may be 
-%% defined in a list. It is recommended that the list be IANA registered so 
-%% that packages that extend the list can be defined without concern for 
-%% conflicting names.
-%% 
-%% 
-%% 12.4	Identifiers
-%% 
-%% Identifiers in text encoding shall be strings of up to 64 characters, 
-%% containing no spaces, starting with an alphabetic character and consisting 
-%% of alphanumeric characters and/or digits, and possibly including the 
-%% special character underscore ("_").
-%% 
-%% Identifiers in binary encoding are 2 octets long.
-%% 
-%% Both text and binary values shall be specified for each identifier, 
-%% including identifiers used as values in enumerated types.
-%% 
-%% 
-%% 12.5	Package registration
-%% 
-%% A package can be registered with IANA for interoperability reasons. See 
-%% clause 14 for IANA considerations.

-%% Purpose: This package defines signals to generate audio tones.
-%%          This package does not specify parameter values. It is

-%%          as an individual signal with a parameter, ind,
-%%          representing "interdigit" time delay, and a tone id to
-%%          be used with playtones.  A tone id should be kept
-%%          consistent with any tone generation for the same tone.
-%%          MGs are expected to be provisioned with the characteristics
-%%          of appropriate tones for the country in which the MG is located.

-%% Name:  native -  Pseudo package  
-%% Version: 1
-%% Extends: None
-%% Purpose: Native tags for media stream properties
-%%
-%% Parameters for Local descriptors and Remote descriptors are
-%% specified as tag-value pairs if binary encoding is used for the
-%% protocol.  This annex contains the property names (PropertyID), the
-%% tags (Property Tag), type of the property (Type) and the values
-%% (Value).Values presented in the Value field when the field contains
-%% references shall be regarded as "information". The reference
-%% contains the normative values.  If a value field does not contain a
-%% reference then the values in that field can be considered as
-%% "normative".
-%% 
-%% Tags are given as hexadecimal numbers in this annex. When setting
-%% the value of a property, a MGC may underspecify the value according
-%% to one of the mechanisms specified in section 7.1.1.
-%% 
-%% For type "enumeration" the value is represented by the value in brack-
-%% ets, e.g., Send(0), Receive(1).
