The tiff format currently accepted by ipp is too broad
in scope for fax server applications. ie it has provisions
for jpeg etc which are too complicated for a simple ipp
fax server. Instead we would like to use TIFF-F which is
currently an ietf draft. I would like to know how an ipp
server which can accept only a TIFF-F format can convey
this capability information to an ipp client.
