RE: I-D ACTION:draft-ietf-fax-esmtp-conneg-06.txt

This is really a minor editorial suggestion. The example
in section 9.2

     S: 250-CONNEG (&(image-file-structure=TIFF-minimal)
     S: 250-CONNEG   (MRC-mode=0)

should say

     S: 250-CONNEG (&(type=image/tiff)
     S: 250-CONNEG   (image-file-structure=TIFF-minimal)
     S: 250-CONNEG   (MRC-mode=0)

because there is some possibility of using image/tiff
or image/tiff-fx, or at least it is not clear which is
mandated by the other parameters.

The example in section 9.1, instead of

        Content-Convert:
           (&(image-file-structure=TIFF-minimal)

could say

        Content-Convert:
           (&(type=image/tiff-fx)
             (image-file-structure=TIFF-minimal)

and the example in section 9.3, instead of

       (&(image-file-structure=TIFF-minimal)
          (MRC-mode=0)

could say
       (&(content-type=image/tiff-fx)
         (image-file-structure=TIFF-minimal)
          (MRC-mode=0)


In addition, the examples in section 9.1 and 9.2 which currently
say "RFC 2822 message with MIME Content-type:TIFF-FX"
should be changed to 
    "RFC 2822 message with MIME content-type: image/tiff-fx".
since both examples use JBIG which is consistent with image/tiff-fx.
