Changes to I-D

• Latest changes as discussed on the WG mailing list:– Subscribing to multiple DPs in one

SUBSCRIBE request• Specification does not prevent anyone from doing

so, but neither does it condone this behavior.

• Aggregation of multiple DPs in a set is a nice option for those services which require a logical OR of the DPs (presence, for example).

Changes to I-D• Resolution on the WG email list:

– The protocol allows a subscriber to subscribe to a set of DPs.

– A NOTIFY is sent when any one of the DPs becomes active.

– The subscription is considered spent after the notification; a new SUBS will be needed to resurrect the subscription.

• This behavior is scoped as a MAY (leaving it to the discretion of the service provider on how to best provide the service).
