<dd>The onfocus and onblur events may
also be used with the <samp class="einst">A</samp> and
<samp class="einst">AREA</samp> elements.
<dt><a href="sgml/sgmldecl.html">Section 20</a>
<dd>The SGML Declaration for HTML 4.0 must be modified slightly
to support hexadecimal numeric character references.
The lines:
<PRE>
DELIM
GENERAL SGMLREF
SHORTREF SGMLREF

<P>must be changed to:

<dt><a href="sgml/dtd.html">Section 21</a>
<dd>The <samp class="einst">HR</samp> element should
also take the <samp class="ainst">lang</samp>
and <samp class="ainst">dir</samp> attributes. These are
noted as being defined elsewhere at the element's definition,
but were left out of the DTDs.
<dt><a href="sgml/dtd.html">Section 21</a>
<dd>The <samp class="einst">OBJECT</samp> element's
<samp class="ainst">archive</samp> attribute is defined
in the DTD as taking a value of type %URI". This is
incorrect: the value may be a space-separated list
of URIs (as indicated in the definition of the
attribute and in the DTDs comment).
<dt><a href="sgml/dtd.html">Section 21</a>
<dd>The <samp class="einst">FORM</samp> element's
DTD fragment should include a definition for the
<samp class="ainst">accept</samp> attribute, which is
listed in the element's definition. The definition
should be the following:</p>
<PRE>
accept-charset %Charsets; #IMPLIED -- list of supported charsets --
<PRE>
<samp class="ainst">archive</samp> attribute is defined
in the DTD as taking a value of type %URI". This is
incorrect: the value may be a space-separated list
of URIs (as indicated in the definition of the
attribute and in the DTDs comment).
<dt><a href="appendix/notes.html#h-B.4.1.1">Section B.4.1.1</a>
<dd>The specification reads, "Blank lines are not permitted."
Blank lines are permitted in the robots.txt file, just not within
a single "record". Note that the specification doesn't define
record.
<P>Further down the page, the specification reads, "There must
be exactly one "User-agent" field per record."
In fact, there can be more than one User-Agent field
in the robots.txt file, just not more than one per record.
