I'd just add that one reason to make this connection, beyond avoiding
fiddly corner cases already studied in the RDF world, is to make it 
clear that there are a range of existing RDF vocabularies out there 
which can now be plugged straight in to XHTML2 documents. The pages at 
http://www.schemaweb.info/ ->
...give a partial directory of these, and there are others in progress
(eg. work at icra.org to migrate their content labelling efforts to have
an RDF representation).
