This document describes an extension to the Session Initiation
Protocol (SIP) defined by RFC 3261.  The purpose of this extension is
to provide an extensible framework by which SIP nodes can request
notification from remote nodes indicating that certain events have
occurred.

Note that the event notification mechanisms defined herein are NOT
intended to be a general-purpose infrastructure for all classes of
event subscription and notification.

This document represents a backwards-compatible improvement on the
original mechanism described by RFC 3265, taking into account several
years of implementation experience.  Accordingly, this document
obsoletes RFC 3265.  This document also updates RFC 4660 slightly to
accommodate some small changes to the mechanism that were discussed
in that document.  [STANDARDS-TRACK]
