I can't speak for Paul, but I doubt that is what he meant. I'd say a
closer example would be the way in which ID attributes establish identity
in a document (i.e. "distinct existence").

I can't go along with that notion, Arjun. I say that markup documents
establish existence and identity by the existence and context of elements.
An ID can make for more robust references (in case of editorial changes) or
more convenient ones or more efficient code, but it is not the essence of
the thing.
It is different with RDF, where there are roles for both nodes identified by
an identifier and nodes identified by their context (anonymous nodes, I
mean).
