>> As you may have noticed in the most recent draft of Finishing 2.1, Ira and I added a new "printer-finisher-supplies" attribute to convey information about finisher supplies, which was absent before. It is structurally similar to "printer-finisher" but contains mappings from "finSupplyTable" / "finSupplyEntry" rather than "finDeviceTable" / "finDeviceEntry".
>> But one of the fields that we added in that first draft was a field for "finSupplyDescription". This is inconsistent with how we support "finDeviceDescription" in 5100.1 - that OID from RFC 3806 is conveyed in IPP via a separate IPP attribute "printer-finisher-description 1setOf text(MAX))". The difference seems to be that the key/value pairs in "printer-finisher" are non-localized, whereas "finDeviceDescription" is a localized string, so "printer-finisher-description" contains localized strings. But this strikes me as odd - we have "printer-strings-supported" now, which could contain localized strings that don't have to be conveyed via IPP attribute values directly.
>> So, how to support "finSupplyDescription"? There are 3 different ways I can imagine:
>> 1. Keep the mapping of "finSupplyDescription" in "printer-finisher-supplies", and embed a localized string within the value of "printer-finisher-supplies"?
>> 2. Keep the mapping of "finSupplyDescription" in "printer-finisher-supplies", but have the value be a key into a string in the string catalog pointed to by "printer-strings-uri"?
>> 3. Remove the mapping of "finSupplyDescription" from "printer-finisher-supplies" and instead be consistent with "printer-finisher" / "printer-finisher-description" by creating a new "printer-finisher-supplies-description" attribute that is syntactically nearly identical to "printer-finisher-description".
>> In this next draft I will do #3 because I can copy / paste quite easily. But I'm not confident that is the right choice.
>> Thoughts?
