True, XSL-FO is defined for only one process. Cross references used for
page number citations are to locations inside of the area tree, and there
is only one area tree in a process.

Would you accept a single PostScript file with both volumes, the second one
starting at page 1, and splitting the resulting file in two? Or creating a
PDF from the PDF and then splitting the PDF into two using a publicly
available PDF library like iText?
Because the process works over only a single FO file you will get your
"cross-volume" references resolved correctly.
My approach would be three sets of pages in one output FO file: volume 1, a
magic one-page signal file, then volume 2. I would then produce the PDF
from the PostScript and write a Python program accessing the iText library
in Java through Jython, streaming the pages of the PDF to a volume 1 output
file, tripping over the magic page as a signal to start volume 2, then
putting the rest of the pages of the PDF file out to a volume 2 output
file. I suppose if I really needed PostScript results I could probably go
from the PDF to PostScript, but I've never researched how that might be ...
of course if there were a library that split PostScript files then I would
just split the result and not bother with the PDF.
It would be totally automated and unattended and result in two distinct files.
I hope this helps!
