And of course content models and class memberships might change as

I prefer your initial suggestion.

I think all of those are good points. Though with the last I would hope 
that this would fit in with any changes we do make to ODD eventually. 
(but of course we can't predict that?) I've been trying to think of 
flaws with this setup which would cause problems.  The only anxiousness 
I have is something to do with what it means for processing if an ODD 
seems to be using both inherited and explicit models simultaneously.
