All,

 Alan has talked to some of the key contributors to the draft at the 
IETF80 with regards to the changes, and as far as I know there 
were no objections with the way forward. 

 That being said, if we don't hear any objections within a week, 
we will see it as a consensus and proceed the draft forward, 
so if you have any objections or comments to the changes 
indicated in Alan's message below provide your comments. 

 Many thanks & regards
  Shida (as chair)
