No, it is not. That would be in order delivery.
There are protocols and contracts which mandate in order delivery - xmpp
is not one of them though.

I think the assumption here is that in order processing will immediately
result in in order delivery - which is a simplistic scenario.
Anyway, the point is - since xmpp does not mandate in order delivery : I
am not sure why 47 is trying to mandate it - especially since seq number
can be used for message re-ordering in case of out of sync delivery.
