Yeah, that thought occurred to me 10 secs after I hit post.   I blame
Monday.

I'm not fluent on RDF,  but taking that statement at face value: is the
existence of b-node an assertion of non-addressability, or just
non-addressibility within a given context?  Either seems problematic to me.
But maybe this one's better left for the RDF list; I don't want to load
xml-dev with idle RDF questions.  You can help me to the proper Draft, if
you want.  Or the proper draft would be better; make it a pint.

Hmmm...  I think this sidesteps the question nicely.  :-)    I don't think
it's possible to come up with a general or multitude of conventions to
disambiguate cross-context boundaries so easily.  It comes back to needing
contractual understanding between parties: a common perceptual framework.

But here we are again at the beginning of this permathread,  so maybe it's
time to hope off the circle until the next tangent approaches.  In 'bout
three months, I reckon.
