I also have off-the-list conversation with Daniel Van Geest, who made some good 
proposals,
which I would also like to include in the draft if the WG agrees.

1. Specify that auth announcements are included into the SUPPORTED_AUTH_METHODS 
notification
   in the order of their preferences for the sender. This doesn't break 
anything (the receiver is free to ignore the order),
   but might help it to make the best choice.

2. Clarify that peers may send the SUPPORTED_AUTH_METHODS independently of 
whether it was received
   (this is not a negotiation). This is what actually the draft says now, just 
stress this for clarification.

3. Specify interaction with RFC 4739 (Multiple Authentication Exchanges in the 
Internet Key Exchange (IKEv2) Protocol).
   In particular. allow sending multiple SUPPORTED_AUTH_METHODS notifications 
in a message
   (also add a clarification that if multiple SUPPORTED_AUTH_METHODS 
notifications are included in a message
    and the receiver doesn't know why, the all included announcements form a 
single list).

(speaking as individual)

I'm okay with these changes.

Paul
