Right. I was not suggesting that a URI be overloaded to denote
both a graph and a serialization of that graph (document).

I was simply suggesting that the approach Dan presented seems
analogous to making assertions about the graph in which statements
occur, from which one can infer things about those statements.

I.e.

IF the source of some graph X is Y
THEN any statement S in X has a source Y

being analogous to

IF the source of some RDF/XML instance X is Y
THEN any statement S serialized in X has a source Y

etc.
