[MFD] Issue to resolve before publishing v1.111 <Response Requested>

Hi Pete and Nancy,

I generally agree with your conclusions, but...one question.

What are the required semantics of, e.g., the duplicated
DocumentFormatSupported and DocumentFormatDefault
(in JobTicket capabilites and Service description elements)?

Does changing one change the other?

The IPP intent of XxxSupported and XxxDefault in the
PrinterDescription were to allow Administrator control.

Does the Administrator have to set them both places?
(This reminds me of IPP parallel attributes yuckiness.)

Cheers,
- Ira
