Hi Mike,

If you really think that we're going to need not just a subset of
an existing raster format, but actually to (re)define a raster
format, then we're going to have to add a 3rd spec.

Because the SC will want a separate document, because the
PWG prototyping requirements for document formats are much
higher - i.e., a full coverage implementation, example files, and

Both PWG PDF/is and PWG XHTML-Print went through this
more stringent process.

For PDF/is, the principal editor Rick Seeler (Adobe) just
implemented every feature as the design firmed up in his
sample documents and demonstrated correct behavior with
Acrobat Reader and another application - he also formally
collaborated with the PDF/A folks about the nuts and bolts.

A raster format is much simpler than PDF but if we bury it in
the one standards-track IPP EW spec, then that whole spec
will be held up in Prototype status by the more stringent
process - not desirable.

I suggest, if CUPS Raster is the starting point then Apple
and CUPS team revise the CUPS Raster format officially
(with a named variant?) to cover the IPP Everywhere
mobile requirements and then let the PWG IPP EW just
reference that revised format.

The new raster format could still be done *with* the PWG,
 it's just not ideal *in* the PWG (which has put the "don't
develop any new document formats" in most every project
charter for a decade).
