This is NOT a choice. If you want the localized description, then
it MUST be in a separate IPP attribute (like existing mappings
for Alert, Input, Output, etc. from Printer/Finisher MIB).
This is not just a style issue. This is a strict IPP requirement that
a given attribute is either completely a localized IPP datatype (text)
or is not localized (octetString).
Prior art in MIB to IPP mapping had a good reason.
