No worries Pete! Do you agree with Ira about my understanding?

I'll file an erratum for this in the event that we (some day) handle PWG specification errata.

Smith,
Sorry about that.  I guess we should have used “inherited” and “overridden” in the job/document attribute discussions.

Hi Smith,
You got it right.
Remember first there were *only* Job attributes in IPP (no Document
object) and much later there were Document attributes.  And the word
"default" got conscripted into service in admittedly a very different
meaning (not pre-configured by an Admin but submitted by a Client).
A clarifying paragraph that contrasts these two uses of "default"
(i.e., apples and camels) would be a worthwhile errata to this spec.
Cheers,
- Ira

Greetings,

Perhaps since I wasn't involved in the creation of PWG 5100.7, I'm having difficulty understanding the meaning of its section 5.2 "Job Description attributes that are defaults for the Document(s) in the Job". I don't quite understand how to even parse its title. Does this mean that 5100.7 is prescribing that the Printer MUST use these Job Description attributes' values as the values for the corresponding Document Description attributes in the case where the Client hasn't overtly specified values for the individual Document objects in a Document creation operation? The use of "default" in this context seems different than the "xxx-default" convention from RFC 8011 etc.
