This document provides a mechanism to negotiate the transfer of one
or more files between two endpoints by using the Session Description
Protocol (SDP) offer/answer model specified in RFC 3264.  SDP is
extended to describe the attributes of the files to be transferred.
The offerer can describe either the files it wants to send or the
files it would like to receive.  The answerer can either accept or
reject the offer separately for each individual file.  The transfer
of one or more files is initiated after a successful negotiation.
The Message Session Relay Protocol (MSRP) is defined as the default
mechanism to actually carry the files between the endpoints.  The
conventions on how to use MSRP for file transfer are also provided in
this document.  [STANDARDS TRACK]
