> The changes are:
> 1. Changed Hold-Job, so that it does NOT return an error if

> specifies "job-hold-until"='no-hold', but rather puts the job into the
> pending state. Same if the named time period has already started.
> (The "job-hold-until" remains an OPTIONAL operation attribute
> to support).
> 2. Fixed the typo in the first line after the table in

> attributes in Set 1 ..."
> 3. Added the following Security section:
> 5 Security Considerations
> For the job operations in Set 1 (Section 2), the requesting user must
> either be the submitter of the job or an operator or
> administrator of the
> Printer object (see [ipp-mod] Section 1). Otherwise, the IPP
> object MUST
> reject the operation and return: 'client-error-forbidden',
> 'client-error-not-authenticated', or 'client-error-not-authorized' as
> appropriate. See [ipp-mod] Section 8.3 on the two ways that
> the client
> MUST specify the user who is performing each IPP operation.
> For the printer operations in Set 1 (Section 4), the
> requesting user must
> by an operator or administrator of the Printer object (see [ipp-mod]

> Printer object are not specified in either [ipp-mod] or this document.

> >>5. Made the following changes to the Restart-Job operation:
> >>a. added the OPTIONAL "job-held-until" operation attribute,

> >>or 'processing-stopped' states.
> >>c. Added the 'job-restartable' value to the
> "job-state-reasons" attribute
> >>to indicate when a job is restartable using the Restart-Job
> >>6. Clarified the "job history" concept as an OPTIONAL sub-state of
> >>'aborted', or 'canceled' job states. If the "job history"
> concept is
> >>supported, clients may query such jobs using the
