Seems to me that this makes sense only if the DTD is not just 
recommended for +RDFa, but *required* for it. Otherwise, even a 
bloodhound won't be able to get back from the document to the spec 
when the DTD is ignored or has gotten lost. Maybe I'm not following 
all the subtleties here.

What's wrong with the namespace way of doing it?
