I think of it as a name of an actual resource that resides in the
underlying RDF graph.  The  last part - for me - is the more important
distinction.  I guess my question is what is an example use case of a
URI reference to a resource that does not exist in the RDF graph?
Perhaps a BNode reference, but I don't think we make that distinction
now. If you are matching a resource by it's name you would probably
want to do a string comparison (which for me is the main use case for
needing to be able to refer to literal strings that do *not* exist in
the underlying graph):

filter(all(),'contains(.,'rdf-syntax-ns'))   -> all first class rdf resources
