Great! If this is the case (and I think it is, except for content models, as
you noted), I think we can move on to other issues.
I'd like to see the RDF-aware on this list continue to make input whenever we
stray into territory that seems impossible to reconcile with a transformation
into RDF, but this 'RDF in a Nutshell' gives us a useful guideline for future
Does it seem reasonable to proceed, keeping a lookout for RDF without chaining
ourselves to its (apparently unstable) syntax?
Let me (or the list) know. I think we're ready.

Sounds like a good challenge. Let's get to work!
