Subject: [Sip] dialog state model for SUBSCRIBE / NOTIFY usages

RFC4235 defines a dialog state model for INVITE usages, and explicitly declares non-session dialogs out of scope

Two questions:
1) is any work planned for a definition of the dialog state model for non-INVITE usages?
2) For SUBSCRIBE/NOTIFY, it would appear that a mapping is possible. In the common case (assuming no 1xx responses) the Subscriber would move from TRYING to CONFIRMED upon reception of 2xx to SUBSCRIBE, and the notifier from TRYING to CONFIRMED upon sending the 2xx response to SUBSCRIBE. Any thoughts on this?

Regards,

Jeroen
