Looking back over your earlier reply, I'm still having trouble reconcil=
ing
these sentences:
> Note, even if it [attributes-charset] is present in a job attributes =
group it
does not affect the charset of those attributes. All attributes in the=
entire
response are in the charset specified by attributes-charset in the oper=
ations
attribute group...
>Note that in the example attributes-natural-language is in one of the =
job
attribute groups in order to override the natural-language in the opera=
tion
attributes.
The attributes-charset in the operations attribute group cannot be over=
ridden
but the attributes-natural-language can?

Subject: Re: IPP> PRO Section 9.7 vs. MOD section 4.3: need clarifica
Attributes-charset and attributes-natural-language must be in the opera=
tion
attributes group
for each request and each response. This implies that the Printer must=
support
these job
description attributes in order to show what values were sent with subm=
it-job
operations.
Thus they are MANDATORY.
The job attributes group contains values of job attributes. For the Pri=
nt-Job,
Print-URI,
Create-Job, Send-Document, Send-URI operations, there is no need for th=
e job
attributes
group to contain the attributes-charset and attributes-natural-language=
of the
job because they
normally have the same value the ones in the operation attributes group=
, and
those are the
important values for the response anyway. It was a judgement call as to=
which
attributes
to return automatically. We picked likely useful ones.
For Get-Job-Attributes and Get-Jobs, attributes-charset and
attributes-natural-language
would be present in the job attributes group only if the client had nam=
ed them
explicitly
or implicitly in the "requested-attributes" attribute in the request. =
Their
values might differ
from those in the operation attributes group, especially if the job
belonged to
someone else.
