Abstract

   This document registers the message/sipfrag Multipurpose Internet
   Mail Extensions (MIME) media type.  This type is similar to
   message/sip, but allows certain subsets of well formed Session
   Initiation Protocol (SIP) messages to be represented instead of
   requiring a complete SIP message.  In addition to end-to-end security
   uses, message/sipfrag is used with the REFER method to convey
   information about the status of a referenced request.
