    abstract =  {This document presents a SIP event package for subscribing to a buddy list. A buddy list is a collection of presentities that a subscriber is interested in learning presence state for. Instead of the subscriber sending a SUBSCRIBE to each buddy individually, the subscriber can subscribe to their buddy list as a whole, and then receive notifications when the state of any of their buddies changes.},
