[Standards] 0237: Roster Sequencing

[Pedro Melo]

Hi,

I think version 0.3 is very god and clean...

A minor note: when the client receives the response with an empty  
query (example 5, the roster has changed but the deltas will be  
pushed later), I think we should mention to client developers that  
their cached sequence number should not be updated. In this scenario,  
the cached sequence number will be updated with the following pushes.

Maybe this is stating the obvious, but when we receive the full  
roster in the reply, we must update the cached sequence, and when we  
receive the empty version we must not.

Maybe an implementation note?

Best regards,
