I was hoping you would say that.  :-)

The original question is "do you personally have a requirement that a 
document with embedded RDFa always emit the same triples, regardless of 
its progeny?".  It is hard to categorically defend a yes answer to that 
question, but on the far narrower question of how to deal with things 
that have a doctype of xhtml which are served as text/html, the answer 
is much easier to defend.
