wonderful!
as the resources that RDF *refers to* can actually be anything,
they could be pieces of RDF syntax and as such resources that
RDF can *use* as well
this could happen after *getting* them from the Web e.g. using HTTP
and it doesn't matter that the fragment is not in the GET header
and that we get back all the triples in that RDF document because
one can always assert more because things are monotonic in RDF
