Technical Summary
This document is a revised version of RFC 2301.  The revisions are
based on discussions and suggestions for improvements that have
been made since RFC 2301 was issued in March 1998, and on the
results of independent implementations and interoperability testing.

This RFC 2301 revision describes the TIFF (Tag Image File Format)
representation of image data specified by the ITU-T Recommendations
for black-and-white and color facsimile. This file format
specification is commonly known as TIFF-FX. It formally defines
minimal, extended and lossless JBIG profiles (Profiles S, F, J) for
black-and-white fax, and base JPEG, lossless JBIG and Mixed Raster
Content profiles (Profiles C, L, M) for color and grayscale fax. 
These profiles correspond to the content of the applicable ITU-T
Recommendations.  In addition, two MIME sub-type registration
documents are part of this request for advancement to draft standard:

draft-ietf-fax-tiff-fx-reg-v2 (image/tiff-fx) updates RFC 3250.
RFC 3302 (image/tiff).
Working Group Summary
These documents are products of the Internet Fax Working Group.  There
has been an ongoing discussion about the validity of the implementation
testing, specifically to confirm that at least two independent
implementations of Profile M have been developed and demonstrated.
Protocol Quality
These documents have been reviewed for the IESG by Scott Hollenbeck.
