But isn't this one of the main functions of RDF?

doh - yes of course :-) - and your explanation of URI+FRAG is what I
actually meant to say, so no argument here either.

But when you say

it's not the expansion I have a problem with, it's whether or not we have a
language we can use to describe the expanded universe.

Does this mean that if I represent a graph in rdf/xml inside an html
document by putting some triples inside rdf tags it has a completely
different meaning to a graph expressed in exactly the same way but served as
an .rdf document?
