Two separate models for conveying instant messages have been defined.
Page-mode messages stand alone and are not part of a Session
Initiation Protocol (SIP) session, whereas session-mode messages are set
up as part of a session using SIP.  The Message Session Relay Protocol
(MSRP) is a protocol for near real-time, peer-to-peer exchanges of
binary content without intermediaries, which is designed to be
signaled using a separate rendezvous protocol such as SIP.  This
document introduces the notion of message relay intermediaries to MSRP
and describes the extensions necessary to use them.  [STANDARDS TRACK]
