Abstract

   This document defines the watcher information template-package for
   the Session Initiation Protocol (SIP) event framework.  Watcher
   information refers to the set of users subscribed to a particular
   resource within a particular event package.  Watcher information
   changes dynamically as users subscribe, unsubscribe, are approved, or
   are rejected.  A user can subscribe to this information, and
   therefore learn about changes to it.  This event package is a
   template-package because it can be applied to any event package,
   including itself.
