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).
