Thanks, Bob, I think I get it now.
Maybe your answer also provides a clue to my next question:
If attributes-charset and attributes-natural-language Job
Attributes are MANDATORY according to MOD/4.3, why aren't they
MANDATORY in "Group 3: Job Object Attributes" under
in MOD/22.214.171.124 "Validate the presence of a single occurrence of
Could it be that the word MANDATORY has different meanings in
4.3: MANDATORY ... attribute[s] MUST be supported by Printer
If it is not indicated as MANDATORY, then it is OPTIONAL
126.96.36.199: MANDATORY attributes [are those] that an IPP object
support and that a client MUST supply
It's still not clear to me.

If I understand your question correctly, I think that you have
having the same
that many other people have had about the word "MANDATORY". It
the "Printer" must support the attribute. It does NOT mean that
be included in each request/response.
In this particular case, attributes-charset is MANDATORY, i.e.
support the attribute, but in the get-jobs reponse it MUST be in
group and it is only in each job attribute group if the client
attribute via the
requested-attributes attribute in the request. Note, even if it
group it does not affect the charset of those attributes. All
response are in the charset specified by attributes-charset in
group, which I still believe must be first in that group (a
change we need to
to the model document).
Note that in the example attributes-natural-language is in one
of the job
groups in order to override the natural-language in the
have been implementing IPP, I have come to believe that this was
a bad idea.
requires a special ordering, i.e. attributes-natural-language
must precede all
attributes if processing is to be simple.
