Hi Glen,
I respectfully disagree with your whole premise.
The PWG collaborated very successfully with Adobe
to develop PWG PDF/is - a subset and a profile of
Adobe PDF.
While PDF/1.7 later became the ISO 32000 standard,
in 2004 the PWG was delighted to collaborate with our
lead editor Rick Seeler from Adobe on PDF/is.
I see no reason to treat PWG CUPS Raster any
differently.
Names of attributes (prefixes) are probably suitable
discussion topics.
But the idea that PWG should only specify a PWG raster
format from scratch would set a bad precedent.
Cheers,
- Ira
