I agree that we need to make conformance checking useful, of course. I 
disagree that a blank <meta/> is necessarily a problem. Maybe the author 
wanted to add some attributes dynamically later. Maybe he wants the DOM of 
all his pages to be equivalent and at that point in his pages there simply 
is no metadata to give.

The difficulty is in walking the fine line between useful and 
over-constrained. For example, the fact that <ol></ol> is invalid in HTML4 
is a real problem.
