[Standards] Proposed XMPP Extension: Roster Versioning

[Richard Dobson]

Thanks for taking the time for the explanation, whilst I still think it 
would be advantageous for clients to not gage any meaning from the 
version ids (or whatever we are now going to call them) and just leave 
all the logic to the server to deal with, i'm not too bothered as to 
what format they are as as myself and others here have pointed out its 
pretty much a server implementation issue and as Pedro mentioned the 
"MAY be a unique identifer that is opaque to the client but understood 
by the server" statement would seem to keep things open and allow enough 
flexibility for us to do things in the best way for our implementations 
(and luckily if I do choose to implement the ids as the increasing 
integers it will be very easy and just a small change to the section 
that is currently generating the timestamps).
