Technical Summary 

This document specifies a way to create subscription to a list of
resources in SIP. This is achieved by including the list of resources in
the body of a SUBSCRIBE. Instead of having a subscriber send a SUBSCRIBE
for each resource individually, the subscriber defines the resource list,
subscribes to it, and gets notifications about changes in the resources'
state using a single SUBSCRIBE dialog. 

Working Group Summary 

The document was originally produced by the SIPPING working group, but
was transferred to the SIP working group due to the need to define a new
option tag, in conformance with RFC 3427. There is consensus in the WG to
publish this document. 

Document Quality 

There is a strong requirement from OMA for a SIP solution in this area. 

Personnel 

Keith Drage is the document shepherd for this document. Cullen Jennings
is the responsible Area Director.
