Harry and Jay,


It would be real helpful if you both could take a couple of minutes and
list what complexity in the current Model document you are most concerned 
about.


Then we could consider doing something about it.  However, just a general
concern about complexity is hard to respond to (and easy to ignore).


Thanks,
Tom
