I'm worried about how Alice can send Bob a dataset in which the graph names denote their graph (and in which she is asserting the triples in the default graph).   How can Alice communicate this intent to Bob?    Doing it out-of-band is of course possible (she calls him on the phone), but that's very messy.   Can she do it in-band, such as by adding a magic triple to the default graph?     Unless that's licensed by the RDF Recommendations, I don't think so.   If the RDF Recommendations say all the triples/quads in a dataset are meaningless (as they currently do), then Bob isn't licensed to consider them as conveying Alice's intent.
