[IPP] JPS2: job-creation-attributes-supported and requesting-user-name attributes

[Michael Sweet]

Ira,

I mainly ask because JPS2 is pretty specific about what keywords can be listed for job-creation-attributes-supported. Operation attributes that are not also job attributes are specifically excluded, however in the case of requesting-user-name there *is* a mirror job attribute called job-originating-user-name.

Now, I can't include job-originating-user-name in job-creation-attributes-supported since it isn't an operation or job template attribute. But at the same time I can't (currently) include requesting-user-name because it is only an operation attribute and not something that is exposed as a job attribute.

(FWIW, I am perfectly fine with the "include requesting-user-name" interpretation, I just want it to be the "accepted" interpretation within the PWG...)

Specifically I am wondering about the requesting-user-name operation attribute - normally this gets mapped to the job-originating-user-name job description attribute, however based on the definition in section 10.1 it would seem that "requesting-user-name" attribute should not be listed since it is not (strictly speaking) a job attribute.
