Agreed.

Yes, it does, because technically a graph is a bag.

OK, but check out the very weak meaning given to it by the latest proposal; what examples does this clash with??? > Data types should use a different property to avoid clashes with >existing usage. rdf:value has no model theoretic meaning; any >interpretation of it is application specific. Actually the DT could use something else.
