I think this is about the best you can do with RDF, and it mostly works,
as long as you're careful to make sure the same document is never read
twice.
That is, if you published that first triple on the web, it would become
logically false as soon as two different agents read it.
But as long as you only TRANSMIT it as as a message, leaving the URI
unstated and forcing the receiver to assign a URI using some kind of
unique-symbol generation mechanism, and somehow make sure they never
republish it, then it's probably logically okay.
This probably isn't the best way to design any real system, though.
