[IPP] IPPScan vs IPPSIX issue for "document-format-accepted

Pete,

I will make sure to update the definition of document-format-accepted to state it is an ordered list of formats to accept.

The default value can be operation-specific, so I don't see the need to create a new operation attribute just for scan - let's keep it document-format-accepted for both IPPSIX and IPP Scan and document the default value in the corresponding operations that use it.

Thanks!

It identifies the acceptable formats of the Document data to be emitted by the IPP Scan Service for the Job. It is an ordered list starting with the preferred format.  The IPP Scan Service MUST use the first supported value in the list. The default value that MUST be used,  if left unspecified by the request, is the value of the "document-format-default".

The default is the value of the "document-format-supported" Printer attribute reported by the Proxy in a previous Set-Output-Device-Attributes (section 5.7) request.
