> The Job Monitoring MIB [JobMIB] is functional with any job submission

Can we find a better word or phrase than "functional with" here?
How about something like:
The Job Monitoring MIB [JobMIB] is intended to be implemented in a device
or server that supports any job submission protocol(s).

Need to indicate that traliing SPACES are used for items shorter than 40.

(The MIB describes the trailing spaces once up front.)

Also this description is much different than (but equivalent to) what
is in the Job Mon MIB. Do you think this is better, so we should change
the MIB? The MIB description is:

'9' octets 2-40: last 39 bytes of the host name with
trailing SPACES that submitted the job to this
server/device using a protocol, such as LPD
[RFC-1179] which includes the host name in the job
submission protocol.
octets 41-48: 8-decimal-digit leading zero
representation of the job id generated by the
by the submitting server (configuration 3)
or the client (configuration 1 and 2), such as in
the LPD protocol.
This format is reserved for clients.

I made the comment last meeting that this MIB attribute should be
jobName(23), not serverAssignedJobName(22), but maybe you have changed
your mind. Or the Job MIB needs some clarification for format 9? The
serverAssignedJobName(22) is only for configuration 3, but LPD can
be used with configurations 1 and 2 as well.

For all three formats, need to add a warning that the range of the
IPP "job-id" attribute could exceed 8 characters, so implementors might
want to limit the range of IPP "job-id" to not exceed 99999999.

Yes, '1' is for clients, but it is IPP clients who assign the "job-name",
so change '?' to '1'. Or do we have some confusion about what is meant
by reserved to clients vs. agents?

I think this should be changed from '4' to '8' (which is also reserved
to clients).

ISSUE: Need some discussion here. It would seem to me that an implementation
that supports multiple protocols could assign job ids as the jobs come
in in any protocol. The jobs that are visible via IPP, could either
show all jobs or show only IPP jobs. There is no requirement in IPP that
job-ids step by one. So there could be holes in the IPP job-id values, for
the implementations that couldn't show jobs from other protocols as IPP jobs.
Therefore, I disagree with the last sentence:
> If jobs are to be
> received from multiple sources, jmJobIndex and job-id must be
> independent.

If the jmJobIndex is not the same as the IPP job-id attribute, then
we may need another jobsubmissionID format, so that a client that knows
the IPP "job-id" can find the job. I had hoped that the jmJobIndex
could always be the same as the IPP "job-id" so that we wouldn't
have to add an extra submission id format in which the "job-id" (an integer)
is the input. Though maybe any of the other three ids formats is good
enough?
