It can solve all the problem elegantly and with out any extension and 
violation. And the draft:

http://www.ietf.org/internet-drafts/draft-gaoyang-sipping-session-state-criterion-01.txt

The just can not accept the way "Commit any session parameters that have 
been sucessfully changed", because there are some serious problems beneath 
it's presentational
easy and practical character.
To analyse incorrectness and drawback of other methods bypass the session 
state, another draft has been posted:

http://www.ietf.org/internet-drafts/draft-gaoyang-sipping-session-state-analysis-01.txt

I do not think all people interested in this topic can accept it 
immediately, so I think it should be talked widely.
Any comments/issues/feelings/notions/emotions/emoticons  are welcome.
