Just to quickly clarify the usage of "URI Reference"

URI includes fragments in the current RFC 3986:

   URI = scheme ":" hier-part [ "?" query ] [ "#" fragment ]

When the RDF specifications were released the above new RFC was not a 
web standard yet, so an RDF URI Reference was described in line with the 
then current standard URI RFC, 2396:

   URI-reference = [ absoluteURI | relativeURI ] [ "#" fragment ]

The RDF URI Reference described in the RDF specifications however, is 
compatible (and supposed to be) URI / IRI as described by the 
now-current RFCs.

As far as I know this will be addressed and updated by the new RDF WG.

As for fragments, I'd merely point you to:
