What you want is reified statements, and as Shelley Powers says,
reification is "the RDF Big Ugly." There are plenty of ways to
express what you want to say in RDF, but they won't necessarily be
useful to a reasoner that doesn't have a built-in understanding of
reification. Of course, if your target is other NewsML readers, then
it may not matter, but you seem to want people to be able to use "off-
the-shelf" tools to make complex queries about statements. At the
moment, I don't think that's possible.
It's too bad RDF wasn't designed with the idea that every assertion
should be reified -- even if only implicitly ("foo.rdf" asserts
"bar"). RDF's underlying assumption of absolute truth is a near-
dealbreaker in the context of massive collaborative networks such as
the internet.
