Isn¹t this an implementation issue? The client either speaks 0 or 1. As
long as the server 
keeps track of the version for the session IMHO it does not matter if the
session id is 
shared? The client doesn¹t know about it. Lets say one encounter a new key
and this 
Only triggers a PDU 9, the server sends send out the notification. The
client can but must not
React to it anyhow. If the client reacts, the server sends an end of
update to a version 0
session and all pdu 9 updates to a version 1 session.
I don¹t see a needed wording here. Not yet but IŒm open for enlightenment.
