Maybe I just haven't woken up enough this morning yet, but I'm not
quite sure what all of this means.

So I'll restate the question:

* I write an RDF document by hand.
* I receive an RDF document from someone else.

How do I know it makes sense? How do I know the right
RDF tags have been used, and in a meaningful way?

In otherwords, since an RDF document doesn't have a DTD
(since it uses namespaces), how do I check it's right?
