You'd probably get surpised of the expressivity of XSLT or XQuery or 
Shematron.

For instance, the WAEX [1] result for http://www.w3.org/WAI/ER/tests/ can 
be found at 
http://www.it.uc3m.es/~per/cgi-bin/xslt.cgi?xmlfile=http%3A%2F%2Fwww.w3.org%2FWAI%2FER%2Ftests%2F&level=aaaplus&alt_max=100&title_max=40&th_max=40&option_max=20&ff_max=6&enablerepair=yes

As you can see: from 50+ rules, only two tests fail for 
http://www.w3.org/WAI/ER/tests/:

1.- Some deprecated HTML attributes (transtalable to CSS) remain (list's 
type)

2.- Headings are improperly used (a h2 is used without a preceding h1).

XSLT/XQuery/Schematron/CLiX can provide ready-to-run tests for many 
accessibility conditions from WCAG 2.0. Not only simple tests like the 
ones mentioned above, but also complex ones like the ones checking for the 
existence of label elements describing form fields.

Cheers.
