Resurrecting this thread - forgive me for letting it get a bit mossy.
I've been reading 5100.13 section 10 "Relationship of Impressions, Pages, and Sheets", and also RFC 2911 section 4.2.4 (where multiple-document-handling is defined).
Is the recommendation we are trying to articulate in IPP2IG that an IPP Client wishing to set job collation should do so by performing the job creation operation (Print-Job, Create-Job / Send-Document) with the job template attribute "multiple-document-handling" == "separate-documents-collated-copies" or "separate-documents-uncollated-copies" and not include the "sheet-collate" attribute? It seems that either "separate-documents-collated-copies" or "separate-documents-uncollated-copies" would work, from the description on page 97 of RFC 2911, if there is only one Document in the Job, because the result either way would be a(*), a(*), a(*), … etc.
So really what we are saying is 'Avoid the "sheet-collate" attribute' and really we should deprecate it if possible.
Am I off in the weeds on this?
Should I be merging this in with the discussion about "finishings" and "finishings-col", and then adding in references to Finishings 2.0?
Thanks for your patience,

>>> - The "multiple-document-handling" attribute doesn't seem to have any method of requesting number-up, finishings, sides. The set of keywords defined for that in the IANA registry are all from RFC 2911:

>> The only thing that I could come up with connecting multiple-document-handling to something like N-UP is that multiple-document-handling influences how the documents are handled within a potentially multiple document job, whereas job-collate seems to influence how the entire job is rendered, and so is somehow disconnected from finishings / finishings-col.
>> Finishings operate on sets. So if you specify multiple-document-handling and/or sheet-collate values that treat the copies as a single set ('single-document' + 'uncollated', for example) and request stapling, then all of the copies get stapled together (probably not what you want...)

>> One of the reasons we opted to use multiple-document-handling as the collate/uncollated copies knob in IPP Everywhere is that sheet-collate has some, um, interesting interactions with multiple-document-handling that are not well defined, whereas using multiple-document-handling for single-document jobs avoids that complexity and provides a single knob for all kinds of jobs.
