Technical Summary This document presents an extension to the Session Initiation Protocol (SIP)-Specific Event Notification mechanism (RFC 3265) for subscribing to a homogeneous list of resources. Instead of the subscriber sending a SUBSCRIBE for each resource individually, the subscriber can subscribe to an entire list, and then receive notifications when the state of any of the resources in the list changes. Working Group Summary The SIMPLE working group supported this capability strongly. The document was transferred to the SIP working group because it needed a SIP option tag. There was a delay while reviewing and revising its discussion of identity. The Open Mobile Alliance has expressed a critical requirement for this specification. Protocol Quality This protocol has been tested in SIMPLE interoperability sessions. It was reviewed for the IESG by Allison Mankin. Note to the RFC Editor OLD: Language tags are defined in RFC 1766 . NEW: Language tags are defined in RFC 3066 . Change reference  to a reference to RFC 3066.
