That would mean going down the road of Conformance checker for the
validator and it's not an easy task at all. Right now the validator
checks only the validity of the documents and not the conformance. My
usual favorite example about that is style information.
******************
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<HTML>
<HEAD>
<TITLE>A simple HTML document</TITLE>
</HEAD>
<BODY>
<p style="font-size: 12pt; color: fuchsia">Aren't style sheets
wonderful?</p>
</BODY>
</HTML>
*******************
This document is
_ valid
- not conformant to HTML 4.01
Because we don't know what style sheets language is used for the
document.
Cf: http://www.w3.org/TR/html401/present/styles.html#h-14.2.1
"14.2.1 Setting the default style sheet language"
MUST: « Authors must specify the style sheet language of style
information associated with an HTML document. »
+ « Documents that include elements that set the style attribute but
which don't define a default style sheet language are incorrect. »
How to make it conformant?
* META (SHOULD)
<META http-equiv="Content-Style-Type" content="text/css">
* HTTP Headers
Content-Style-Type: text/css
Maybe a better place to check this kind of things would be the
LogValidator developed by Olivier Théreaux.

How to create New Modules
http://www.w3.org/QA/Tools/LogValidator/Manual-Modules
This last part means you can plug as many modules as you want to the
LogValidator specifically designed for certain tasks.
Many modules could be developed for the benefit of the community.
- SpellChecker
- microformats
- metadata (meta name, link checker)
- etc.
