The explicit URI!

Yes, RDF Schema is a bad example to follow, and yes, the "ID" thing is
a bit of broken markup, but it was put in because of the worries about
the fact that FragmentIDs on XML languages always reference whatever
the XML ID in that language is. Of course, RDF works in such a way
that this is pointless, but obviously this wasn't caught early enough
to purge it from the specification.

TimBL discusses it a bit at the bottom of [1]. I'd advise people to
always use "rdf:about" as a best current practice.
