I can see that leads us essentially to paradox. (of course the set of 
valid xhtml is also infinite).

The spec is written only for valid xhtml, and that seems appropriate, 
but the expectation is that implementations do the right thing with 
invalid xhtml. My own implementation even runs a tidy algorithm on stuff 
that either has an html mimetype or a root element of html

Some of the features we wish to test do require grddl attributes on the 
root element, which leads us to either:
a) tests with invalid input
b) some kind of DTD hackery

To date the WG has been following (a). We're hoping to move test cases 
to last call very soon, and if anyone feels strongly enough about this 
topic, it would be an appropriate area for a last call comment.
