	Title		: Registration Event Package Extension for 
                          Session Initiation Protocol (SIP) Globally

RFC 3680 defines a Session Initiation Protocol (SIP) event package
   for registration state.  This package allows a watcher to learn about
   information stored by a SIP registrar, including its registered
   contact.

   However, the registered contact is frequently unreachable and thus
   not useful for watchers.  The Globally Routable User Agent URI
   (GRUU), defined in RFC YYYY [3], is a URI that is capable of reaching
   a particular contact.  However this URI is not included in the
   document format defined in RFC 3680.  This specification defines an
   extension to the registration event package to include GRUUs assigned
   by the registrar.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
