Maybe IE9 will be the browser that makes real XHTML on the WWW practical.

I would expect any HTML compatibility testing alerts to be issued as 
warnings (not errors), and only if the document was served as text/html 
(perhaps with a "This document did not pass HTML compatibility testing, 
which might be an issue if you serve it as text/html. You may wish to 
<a>see the results of HTML compatibility testing</a>." for 
application/xhtml+xml documents).
