There are relatively small number of standard PDF meta-data keys.  Document number or publication ID is not one of those. There is a "keyword" key which could be adapted for that purpose, specifying "SA22-7832-12" as one of the keyword values, or it could be included as a part of the standard Title or Subject metadata values, but the creators of the PDF documents would have to commit to enforce that usage convention.  Perhaps the inclusion of this in the metadata needs to be submitted as a requirement.

I see a suggestion that Adobe PDF creation tools may have support for creating custom metadata keys, but if true, that doesn't guarantee other utilities designed for "standard" PDFs would interpret them.  LO Writer, and I suspect MS Word as well, has support for specifying "Custom Document Properties" key-value pairs, but these don't appear to be included as part of the PDF metadata when those applications generate PDFs.

Lacking a convention to use a specific metadata key for the manual publication number, the obvious and simplest way to supply the manual publication number in a manner that could easily be extracted from a PDF file is to include the complete designation as part of the file name.

Doe this mean that there is no way to extract it?

Do the PDF manuals for z/OS have the forms code in the metadata? If so, under 
what key.

E.g. ?:

1022 $ pdfinfo z⧸OS\ UNIX\ System\ Services/z⧸OS\ UNIX\ System\ Services\ 
User\'s\ Guide
     | grep -i form
Creator:         AH XSL Formatter V7.1 MR3 for Linux64 : 7.1.4.51036 
(2021-06-14T14:17+09)
Form:            none
1023 $

I find pdfinfo as part of poppler or xpdf.  It might also be in ghostscript.
