   I will pass your email on -
   As far as charter, you yourself have said a number of times that it  
is up to the WG to decide what is rec track and what isn't - I think  
we've certainly met the charter requirements on the design of the  
profiles.  Yes, I have said at other times I'd like to see the  
deliverables rec track, and if it was a perfect world I'd still be  
arguing for the profiles, but as I said in the email that started this  
thread, this was a new realization for me, and took a lot of thought.
