Ian - I owe you an apology - I was frustrated over some of the things 
in our WG that just seemed to be going round and round, and I 
unloaded on you VERY unfairly.  You have been one of the more 
involved people in the WG, you have consistently provided important 
information, you have a principled approach to your arguments, and 
you've shown a willingness to "live with" some things that you don't 
particularly like.  If we all would work as hard on this as you do, 
and would be as careful in our work, then the WG would be even more 
productive than it is.
  I apologize to you for my remarks, and to the whole WG for wasting their time
  Sincerely,
  Jim H
