Hi Mike,
Needs discussion at IPP WG meeting and probably at PWG F2F.
Pete Zehler is understandably not in favor of moving away from the
Printer MIB model of subunit elements - I agree with him.
Bear in mind that the value of "output-bin" is simply the value of
the "prtOutputName" element in Printer MIB - there's no obscurity
about correlation.
And "output-bin" as a sticky Job attribute was a late IPP addition
and is poorly supported (in my experience). "output-bin-default"
has the same value as "prtOutputDefaultIndex->prtOutputName".
Cheers,
- Ira
