        The document defines extensions to the SDP offer/answer model
to enable file transfer as part of SDP-negotiated multimedia
sessions.  It also specifies using MSRP for the actual file
transmission.

    Working Group summary:

        The MMUSIC WG has firm consenses on publishing this document
as Proposed Standard.

    Document quality:

        The document is considered ready for publication.

    An early interoperability test of independent implementations
from various major vendors on an image sharing specification
(which uses the file transfer I-D as a basis) took place
already in 2007 under the auspices of the GSM Association.
The interop event provided useful input for this and other
specifications.

        The document shepherd is Joerg Ott, the responsible AD is
Cullen Jennings.
