Technical Summary
   This document describes an extension to the Session Initiation
   Protocol (SIP) for publishing event state used within the SIP Events
   framework. The first application of this extension is for the
   publication of presence information.

Working Group Summary
  The work on this extension began in the SIMPLE working group, 
   because the requirements were generated in the context of
   presence information.   As a result, there was a great deal of review
   of the serviceability of the extension, before it went to the SIP WG
   for review of its generality and conformance to SIP guidelines.
   There was some debate on architecture, but there was a strong
   support for advancement of this document.
Protocol Quality
  There have been many reviews of the specification, and it has been
   well managed by its editor.  

Allison Mankin reviewed the specification for the IESG.
