Content-Type description in Impl-Guide

James,

Thanks for your comment.

(I changed "Subject".)

Very good!

9. MIME content-types image/tiff and image/tiff-fx

<snip>

   within an image/tiff or image/tiff-fx content type. The image/tiff
   content type should be used when black-and-white image data is
   encoded using TIFF-FX (RFC 2301 "File Format for Internet Fax")
   Profiles S or F, or a subset. The image/tiff-fx content type must be
   used when black-and-white or color image data is encoded using TIFF-
   FX Profiles J, C, L or M and any future TIFF-FX extensions, or a
   subset. The image/tiff-fx content type may be used when black-and-
   white image data is encoded using TIFF-FX Profiles S or F, or a 
   subset.

So, I think it is true.

Anyway, thanks.
