Tom,
There is a Proposed Standard RFC 2302, which "describes the registration of
the MIME sub-type image/tiff. The baseline encoding is defined by [TIFF].
This document refines an earlier sub-type registration in RFC 1528
[TPC.INT]." It is up for Draft Standard, along with other proposed standards
from the IETF Internet Fax WG. The RFC is available at
http://www.imc.org/rfc2302.
tiffplus refers to what was an ID and is now RFC 2301, the TIFF-FX spec.

Richard,
Here is the current image/tiff entry in the IANA registry. Is it ok?

Second question:
Are you suggesting that just identifying the document-format as 'image/tiff'
is insufficient?
For conformance in IFAX using IPP, we may need to specify that image/tiff
includes some particular profile. Or are you suggesting that we need to
specify the profile in the value of the IPP "document-format" attribute in
some way?
Does the submitter (client software) have to identify the profile being used
in what is being submitted to the IPP Printer, or is it sufficient for the
IPP Printer to indicate the profile or profiles that it will accept and
image correctly for documents submitted with the document-format attribute
indicating 'image/tiff'? If the latter is sufficient, we could just add a
Printer Description attribute, say, tiff-profiles-supported, in which the
printer lists the tiff profiles that it supports. Such an attribute would
not be submitted with the document, but would be queriable using
Get-Printer-Attributes.
If the submitter has to identify the profile being passed, then we would
need to add a new Job Template attribute (or may a new Operation attribute?)
that indicates the "tiff-profile" being submitted. This attribute would
only be submitted when the "document-format" attribute also being submitted
was 'image/tiff'.
Comments?
