Jeremy -
   Let me see if I understand - this one, like the annotations 
question is with respect to whether these features of our language, 
which are in OWL Full (by the RDF inclusion principle :->) should 
also be in Owl Lite and Owl DL.
   Is there any implication to our model, complexity, etc. which is 
affected by this?  That is, if we were to add these in Lite, can you 
give some examples of what we could or couldn't do that would effect 
reasoning?
  thanks
  JH
p.s. if you need me to rephrase - can you generate a test case or example?
