<h2>Validate XHTML With A DTD</h2>
<p>An XHTML document is validated against a Document Type Definition (DTD).
Before an XHTML file can be properly validated, a correct DTD must be added as
the first line of the file.</p>
<p>The Strict DTD includes elements and attributes that have
not been deprecated or do not appear in framesets:</p>
<pre>!DOCTYPE html PUBLIC
"-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"
</pre>
<p>The Transitional DTD includes everything in the strict DTD plus
deprecated elements and attributes:</p>
<pre>!DOCTYPE html PUBLIC
"-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
</pre>
<p>The Frameset DTD includes everything in the transitional DTD
plus frames as well:</p>
<pre>!DOCTYPE html PUBLIC
"-//W3C//DTD XHTML 1.0 Frameset//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd"</pre>
<p>This is a simple XHTML document:</p>
<table width="100%" border="1" class="ex" cellspacing="0">
