<TITLE>HTML 2.0 DTD: XMP element</TITLE>
</HEAD>
<BODY>
<H1>XMP</H1>
<p>
The <XMP> and <LISTING> elements are similar to the
<a href="pre.html"><PRE></a> element,
but they have a different syntax. Their content is declared as CDATA,
which means that no markup except the end-tag open delimiter-in-context
is recognized.
</p>
<dl>
<dt>NOTE</dt>
<dd>In a previous draft of the HTML specification, the syntax
of <XMP> and <LISTING> elements allowed closing tags to be treated
as data characters, as long as the tag name was not <XMP> or
<LISTING>, respectively.</dd>
</dl>
<p>
Since CDATA declared content has a number of unfortunate interactions
with processing techniques and tends to be used and implemented
inconsistently, HTML documents should not contain <XMP>
nor <LISTING>
elements -- the
<a href="pre.html"><PRE></a>
tag is more expressive and more consistently
supported.
</p>
<p>
The <LISTING> element should be rendered so that at least 132
characters fit on a line. The <XMP> element should be rendered so
that at least 80 characters fit on a line but is otherwise identical
to the <LISTING> element.
</p>
<dl>
<dt>NOTE</dt>
<dd>In a previous draft, HTML included a <PLAINTEXT> element
that is similar to the <LISTING> element, except that there is no
closing tag: all characters after the <PLAINTEXT> start-tag are
data.</dd>
