No.  Wrong.  In

   <rdf:Description rdf:about="http://example.org/something#foo">

RDF defines the URI to refer to whatever a document of type 
application/rdf-xml would define it to mean.  RDF defines that, 
irrespective of the mime-type of the document it is contained in.

The point here is that there is no single mime-type for 
http://example.org/something.  In general, that URI does not denote a 
representation with a specific mime-type.

Now lets consider a URI that does refer specifically to that representation:

   <rdf:Description rdf:about="rep:text/html:http://example.org/something#foo">

then the RDF denotation of that uriref is exactly the same as the html one.
