The only problem I've had with it is the vague error descriptions. For 
example, it says I can't use div tags in a lot of places, and provides a 
link to the top of some xhtml standards spec document, but doesn't 
actually explain why I can't use a div there (inside an li element for 
example). It'd be great if it could just tell you why something should 
not be used in a certain context. It would make the tool double as a 
kind of an HTML5 educational tool.


Thanks,
