Nifty, maybe.  But I fear that growing dependency on these subtleties of 
RDF/XML syntax may raise the barrier to entry to using RDF.  You, one of 
the more experienced users of RDF, weren't sure about the validity of the 
syntax used.

I think we need to nail down the handling of simpler cases before getting 
too involved in arcane syntax options.  By simpler cases, I mean how are we 
to interpret simple RDF like this:

   <rdf:Description rdf:about="#me">
     <ex:shoeSize>10</ex:shoeSize>
   </rdf:Description>

and

   <rdfs:Property rdf:about="http://example.org/shoesize">
     <rdfs:range rdf:resource="xsd:integer" />
   </rdfs:Property>
