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.
