Hi juha,

i don't think that its part of any standard.
what we observed is that UAs do respect the expires we send with
subscription=active
this acts like the max_expires params, if its out of bounds it corrects the
value and subscribes with that value in expires.
when it send the subscription=active, it will send the expires accepted and
saved in the server.

does that help ?
