A new “job-ids” operation attribute is added to Purge-Jobs and Get-Jobs, as well, to operate on a specified list of jobs, instead of on all jobs.

Or :

This document also defines three new operations - Cancel-Jobs, Cancel-My-Jobs, and Resubmit-Job - and a new "job-ids" operation attribute to be used with the existing Get-Jobs and Purge-Jobs operations. Cancel-Jobs allows an operator/administrator to cancel a list of Not Completed jobs or all Not Completed jobs on the Printer. Cancel-My-Jobs allows a user to cancel a list of their Not Completed jobs or all their Not Completed jobs. Resubmit-Job allows a user to re-process a modified copy of a Retained Job. Get-Jobs with the "job-ids" attribute allows a user to get a list of jobs. Purge-Jobs with the "job-ids" attribute allows an operator/administrator to purge a list of jobs.

and change "Resubmit-Jobs" to "Resubmit-Job"... :)

IPP/2.2 is NOT currently defined, but will include this spec and four others (PWG 5100.3, .5, .6, and .8) and a number of new required operations and attributes. 

Right, and you can probably expect that some IPP/2.1 implementations might implement this spec but not the others. So, what Ira said... :)

Right, you can't combine a list of jobs with any of the other selectors, so combining "job-ids" with "limit", "my-jobs", or "which-jobs" should result in a client-error-conflicting-attributes status code.

client-error-conflicting-attributes

Yeah, I think that is appropriate - require the job-printed-* and conditionally require the job-saved-* "job-state-reasons" keywords. Similarly, require the all but the saved "which-jobs" keywords, where saved is conditionally required.

job-state-reasons: job-printed-successfully, job-printed-with-errors, job-printed-with-warnings, job-resuming, job-scheduling, job-spooling, job-streaming, job-suspended-by-operator, job-suspended-by-system, job-suspended-by-user, and job-suspending are all REQUIRED. job-saved-successfully, job-saved-with-errors, and job-saved-with-warnings are REQUIRED if job save is supported

which-jobs: aborted, all, canceled, pending, pending-held, processing, processing-stopped, proof-print are all REQUIRED. saved is REQUIRED if job save is supported
