Subject: [SIP] draft-ietf-sip-session-timer-04: SDP in re-invite response

Please mention in draft-ietf-sip-session-timer 
that the UAS SHOULD reply with non-changed-SDP 
to a re-INVITE with non-changed-SDP.  
[Notice that I am only asking for a SHOULD since 
the draft currently allows the re-INVITE to 
revive a dead session (even if the sender 
didn't want that to happen).]

I'm requesting it to be explicitly stated in 
the draft because some products that require 
others to send re-INVITE session refreshers 
actually change the origin line in the 200 
response SDP without changing anything else
in the SDP.
