[IPP] media-type names and cotton?

I can live with '-archival', '-bond' and '-cotton' extensions.  Is there
a registration for the extensions or do we register all the compound
names with 'stationery', 'cardstock',  'label' and 'photographic' as the
top level?

	Xerox's request from the Face to Face was to add a registered
media-type name for cotton and I'd supply the details at a later time.
Below are the semantic definitions for archival, bond and  cotton
media-type values we are proposing.  The media weight (i.e. gsm range)
can be ignored since the PWG does not include it in "media-type"
definitions.   I included it because it was available to me from
production printing.


FWIW, we already have "stationery-bond" as a media type, and in general
I would prefer to avoid mixing top-level and suffix names. More comments
inline below...


	New media-type values to register:

	'archival' - A tough, acid-free paper made with an alkaline
buffer.   Extraneous materials (such as sugars, starches and gums) in
the pulp that can cause discoloring and deterioration, are carefully
removed. Physical strength for the paper is ensured by using a long,
high quality fibers such as cotton or flax that enables it to be usable
for long periods. (gsm range 106-169)


Given that the existing photographic media type are often/typically
archival-quality, would it make more sense to treat "archival" as a
common suffix for existing top-level types, e.g.:








	'bond' - A better quality grade of paper that is stronger and
more durable than 'stationary' (gsm range 81-130)


As I mentioned above, we already have stationery-bond.


	'cotton' - A rag pulp based paper which is made up of cotton
fibers (gsm range 75-90)


Do we need a top-level for this too?  "stationery-cotton" (and, if you
think it is necessary, "cardstock-cotton") would seem to capture the
existing usage for this type of media.
