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!
