There seems to be some confusion as far as how to specify jogging between jobs, and when I asked Rainer about it, he asked me to write this question.
It seems very strange to me that a job ticket associated with *one job* can specify, in the Disjointing element, to jog every 5 jobs. Do all later jobs follow this specification? Until a job comes along that says to *not* jog? What about a later job that says to jog every 10th sheet--does that erase the "every 5 jobs" setting?
IMHO, a more reasonable approach would seem to be that a job cannot specify to jog every 5 jobs--that is, that a job cannot affect the jogging of other jobs. However, in that case, what does Disjointing/@OffsetUnit="Jobs" mean then? Does it only mean "please jog before *this* job"? In which case, I guess Disjointing/@OffsetAmount must be 1, or might be ignored?
Another complication with the "Jobs" value is that a reasonable use case would be to jog between each copy of the job *and* at the start of the job. Is it true that asking to jog every copy will also jog before the first copy (and thus before the job)? If that is not true, it seems impossible to get that behavior, since only one Disjointing element can be specified in DigitalPrintingParams. What about jogging every 12 sheets--does that jog before the first sheet (and thus before the job)?
(Note that the latest drafts of JDF 1.6 and XJDF have had Disjointing/@OffsetUnits removed, which was an accident according to Rainer. So to fully understand the above question, you might need to look at JDF 1.5, or wait for 1.6/2.0 to be fixed.)

We need to avoid any job spanning instructions within a job, therefore I agree that we need to clean up the wording for jobs and also that a less granular break always implies a more granular break - e.g a job break is also a document break.
