Schematron or XSLT/XQuery rules can be applied to HTML documents if a HTML 
parser (instead of a XML parser) is being used. For instance, my XSLT-based 
Web Accessibility evaluator [1] can be applied to HTML pages that are not 
XHTML (see the extended interface).

So, my question is: wouldn't be nice to provide formalized expressions 
(based on Schematron or XSLT templates) in the WCAG 2.0 HTML Techniques 
draft? Web developers would have objective and formalized tests instead of 
just subjective prose. Examples are good, but not enough.

I did a few searches in W3C mailing lists archives and found that there 
have been previous attempts at formalised expressions, for example with 
Schematron by Nick Kew 
(http://lists.w3.org/Archives/Public/w3c-wai-er-ig/2001Nov/0031.html).

Also, one of the first comments on the WCAG Last Call Working Draft is also 
about formalising some of WCAG: see 
http://lists.w3.org/Archives/Public/public-comments-wcag20/2006May/0003.html 
, which also mentions Schematron and Relax NG.

Choosing or developing a format for formalised expressions could be the 
objective of a dedicated group, if there are enough volunteers.

Regards,

Christophe
