Dave, this keeps coming up and I would like to tackle it, but Im not sure how, or even if, this XML feature is supposed to map into RDF triples. If the answer is obvious to you, could you briefly explain it, using Ntriples? Many thanks. > >6.

What would rdf:value mean if it wasnt pointing to a literal? For example what relationship between _:x and _:y would this state: _:x rdf:value _:y . _:y rdf:value "10" . ??
