We'd like to propose these new IPP extensions for registration.

Natural Language and Character Set: The "attributes-charset" and
"attributes-natural-language" attributes as described in section
3.1.4.1.

Target: Either (1) the "printer-uri" (uri) plus "job-id"
(integer(1:MAX)) or (2) the "job-uri" (uri) operation attribute(s)
which define the target for this operation as described in section
3.1.5.

Requesting User Name: The "requesting-user-name" (name(MAX)) attribute

Not all attributes are settable.

Set-Job-Attributes Response:

Group 1: Operation Attributes

Status Message: In addition to the REQUIRED status code returned in
