   In our discussion of the compliance level issue there were indeed 
those who said we should have only one level and it should look a lot 
like Owl-lite (go read our archives) - at the time the chairs and the 
WG decided not to hold that specific discussion, however we ruled 
that it was within the scope of the OPEN issue 5.2 [1]  (Guus, if you 
remember differently, please correct me)
   That said, in this particular case, however, I was not referring to 
WG discussion, but to a comment received in our public comments list 
[2] which stated "Forget about OWL-Heavy (for now; maybe forever)" 
and for which I was soliciting feedback from the DAML community, who 
have been users of the DAML+OIL language and would be likely 
candidates to provide feedback on both sides of this issue, making it 
easier for us to have appropriate documentation of whichever decision 
we take when we move on to Candidate Recommendation.

p.s. In future, please be more careful about forwarding mail from 
limited distribution groups to public ones - no harm done in this 
case, but obviously there may be times when the author doesn't want 
to send to a public group.
