I missed the post on XSL-List and would have commented there. I just found
the message in an archive, so I will post my answer below to that list as
well since there will be readers on that list that are not on this
list. Sorry for the duplication.
I don't think you need an extension if you are willing to accept a limit.

I would have thought that page 16 would have zero bars and that page 17
would have been reset to 1 ... but my solution stands if the answer goes
If you don't mind having some "typically maximum limit" and then
accommodating an overflow condition ... say you accept a 256 page limit ...
that no bill will be longer than 256 pages and that if there is one that is
257 or more pages that you accept the XSL-FO formatter throwing an error to
signal the pages were not totally completed.
Create as many <simple-page-master>s as you have combinations of bars (so
either 15 or 16 based on the answer above ... I'll assume 16). Each
<simple-page-master> has a different <region-start> name, say "region-0"
Create a <page-sequence-master> with 256 <single-page-master-reference>
children, in order pointing to masters respectively with
Create your <page-sequence> pointing to the <page-sequence-master> and
including 16 definitions of <static-content> one for each of the 16
combinations of bars, with absolutely positioned block containers with a
<leader> rule in each positioned where you want the folding marks.
Then go ahead and format the document! If there are 257 pages in the one
bill, the formatter will abend and indicate that it has run out of page
geometries for the formatting run. But as long as there are enough
single-page-master-references in your page-sequence-master, it will not
abend and you will get the pattern of marks in the edge of your paper.
Yes, it would be cleaner and there would be no limit if there were a
sub-sequence-repeater object in XSL-FO (how about that as a new requirement
for version 2?) but if you can accept the maximum page count and I've
understood your requirement then I think you've got what you need.
I hope this helps.
