-%% Purpose: YECC grammar for text encoding of Megaco/H.248
-%%
-%%                      DEPRECATED
-%%                      DEPRECATED
-%%                      DEPRECATED

-
-%%----------------------------------------------------------------------
-%% Annex B TEXT ENCODING OF THE PROTOCOL (NORMATIVE)
-%%
-%% B.1 Coding of wildcards
-%%
-%% In a text encoding of the protocol, while TerminationIDs are
-%% arbitrary, by judicious choice of names, the wildcard character, "*"
-%% may be made more useful.  When the wildcard character is encountered,
-%% it will "match" all TerminationIDs having the same previous and
-%% following characters (if appropriate).  For example, if there were
-%% TerminationIDs of R13/3/1, R13/3/2 and R13/3/3, the TerminationID
-%% R13/3/* would match all of them.  There are some circumstances where
-%% ALL Terminations must be referred to.  The TerminationID "*" suffices,
-%% and is referred to as ALL. The CHOOSE TerminationID "$" may be used to
-%% signal to the MG that it has to create an ephemeral Termination or
-%% select an idle physical Termination.
-%%
-%% B.2 ABNF specification
-%%
-%% The protocol syntax is presented in ABNF according to RFC2234.  The
-%% protocol is not case sensitive.  Identifiers are not case sensitive.
-%% 
-%% NOTE 1 - This syntax specification does not enforce all restrictions 
-%%          on element inclusions and values.  Some additional 
-%%          restrictions are stated in comments and other restrictions 
-%%          appear in the text of this Recommendation. These additional 
-%%          restrictions are part of the protocol even though not 
-%%          enforced by this Recommendation.
-%% NOTE 2 - The syntax is context-dependent. For example, "Add" can be 
-%%          the AddToken or a NAME depending on the context in which it 
-%%          occurs.
-%% 
-%% Everything in the ABNF and text encoding is case insensitive. This 
-%% includes TerminationIDs, digitmap Ids etc. SDP is case sensitive as 
-%% per RFC 2327.

-%% Purpose: YECC grammar for text encoding of Megaco/H.248

-%%                      DEPRECATED
-%%                      DEPRECATED

-%% Annex B TEXT ENCODING OF THE PROTOCOL (NORMATIVE)
-%%
-%% B.1 Coding of wildcards
-%%
-%% In a text encoding of the protocol, while TerminationIDs are
-%% arbitrary, by judicious choice of names, the wildcard character, "*"
-%% may be made more useful.  When the wildcard character is encountered,
-%% it will "match" all TerminationIDs having the same previous and
-%% following characters (if appropriate).  For example, if there were
-%% TerminationIDs of R13/3/1, R13/3/2 and R13/3/3, the TerminationID
-%% R13/3/* would match all of them.  There are some circumstances where
-%% ALL Terminations must be referred to.  The TerminationID "*" suffices,
-%% and is referred to as ALL. The CHOOSE TerminationID "$" may be used to
-%% signal to the MG that it has to create an ephemeral Termination or
-%% select an idle physical Termination.
-%%
-%% B.2 ABNF specification
-%%
-%% The protocol syntax is presented in ABNF according to RFC2234.  The
-%% protocol is not case sensitive.  Identifiers are not case sensitive.
-%% 
-%% NOTE 1 - This syntax specification does not enforce all restrictions 
-%%          on element inclusions and values.  Some additional 
-%%          restrictions are stated in comments and other restrictions 
-%%          appear in the text of this Recommendation. These additional 
-%%          restrictions are part of the protocol even though not 
-%%          enforced by this Recommendation.
-%% NOTE 2 - The syntax is context-dependent. For example, "Add" can be 
-%%          the AddToken or a NAME depending on the context in which it 
-%%          occurs.
-%% 
-%% Everything in the ABNF and text encoding is case insensitive. This 
-%% includes TerminationIDs, digitmap Ids etc. SDP is case sensitive as 
-%% per RFC 2327.

-%% Purpose: YECC grammar for text encoding of Megaco/H.248

-%%                      DEPRECATED
-%%                      DEPRECATED

-%% Annex B TEXT ENCODING OF THE PROTOCOL (NORMATIVE)
-%%
-%% B.1 Coding of wildcards
-%%
-%% In a text encoding of the protocol, while TerminationIDs are
-%% arbitrary, by judicious choice of names, the wildcard character, "*"
-%% may be made more useful.  When the wildcard character is encountered,
-%% it will "match" all TerminationIDs having the same previous and
-%% following characters (if appropriate).  For example, if there were
-%% TerminationIDs of R13/3/1, R13/3/2 and R13/3/3, the TerminationID
-%% R13/3/* would match all of them.  There are some circumstances where
-%% ALL Terminations must be referred to.  The TerminationID "*" suffices,
-%% and is referred to as ALL. The CHOOSE TerminationID "$" may be used to
-%% signal to the MG that it has to create an ephemeral Termination or
-%% select an idle physical Termination.
-%%
-%% B.2 ABNF specification
-%%
-%% The protocol syntax is presented in ABNF according to RFC2234.  The
-%% protocol is not case sensitive.  Identifiers are not case sensitive.
-%% 
-%% NOTE 1 - This syntax specification does not enforce all restrictions 
-%%          on element inclusions and values.  Some additional 
-%%          restrictions are stated in comments and other restrictions 
-%%          appear in the text of this Recommendation. These additional 
-%%          restrictions are part of the protocol even though not 
-%%          enforced by this Recommendation.
-%% NOTE 2 - The syntax is context-dependent. For example, "Add" can be 
-%%          the AddToken or a NAME depending on the context in which it 
-%%          occurs.
-%% 
-%% Everything in the ABNF and text encoding is case insensitive. This 
-%% includes TerminationIDs, digitmap Ids etc. SDP is case sensitive as 
-%% per RFC 2327.
-%%
