IMHO compiler warnings are a pass of the "but you should do better" kind.

I am with Shadi for not having a top-level validity level "warning". I 
don't know, when this message is created. But if the problem makes the 
CSS invalid, it should be a (subclass of) fail, if it does not affect 
the validity, it should be a (subclass of) pass. If you can't make a 
pass/fail statement, it should be a (subclass of) cannotTell.
