[IPP] "print-color-mode" or "imaging-color-mode"?

[IPP] "print-color-mode" or "imaging-color-mode"?

Hi,

On reflection, I tend to agree with Andrew that we should
(in general) use the 'imaging-' prefix for our new attributes.

But I *think* we meant the new 'print-color-mode' property
to refer specifically to hardcopy output (print).

I don't think it fits well w/ scan (output image format) or fax.

All - note that we generally *drop* the 'print-' or 'job-' or
whatever prefix in the PWG Semantic Model XML Schema
in order to reuse the "same" (well similar) attribute at more
than one level of the system/service/job/document hierarchy.

Pete - please chime in with your opinion here.

Cheers,
- Ira
