Reverse Blank page numbering
- In our manuals, a chapter always ends on an even page. So I have the
page-sequence defined to insert a blank page when the chapter content ends
on an odd page number - that works.
My question is about page numbering, which appears in the footer. Our style
guide says the last page of content, if an odd page, needs to have special
page numbering, thus:
The chapter content ends on page 75. The footer on page 75 says "75/(76
In other parts of the manual (frontmatter and rearmatter), the same scenario
is treated with "75 (Reverse Blank)". Obviously, I'll create several
So I need a conditional that determines when the content ends on an odd
page, and a way to calculate the next (even) page number. Any ideas or
clues where I can look for code samples? This can't be that uncommon.

odd-or-even="odd" to give you what you want, but the
force-page-count="even" makes the even blank page the last page of the page
sequence (I had mistakenly thought the content page would be considered the
last page of the page sequence) so the condition is never considered true.
On closer examination of the spec, I see in 7.25.6 that any forced page at
the end becomes the "last" page in the sequence for the purposes of testing
page position ... so it is, indeed, not possible to test for "next-to-last"
page in the page sequence.
But I hope the XSL committee is listening or you can take the time to send
your requirement to the xsl-editors@... address. I think you've made a
justification for a "next-to-last" page-position test value (though not
being an implementer I'm not sure what the ramifications are). Wait ...
even that won't help, because just with that you won't be able to say
"next-to-last when last-is-blank", so it is getting too bizarre to try and
So in summary I think you are out of luck and there may not be a concise
addition to propose to the committee for consideration.
>So I need a conditional that determines when the content ends on an oddBecause conditions are processed at transformation time, and your
requirement is only known at formatting time, there is nothing in 1.0 that
can help you.
>and a way to calculate the next (even) page number.Nope ... no calculations can be done on page numbers.
>This can't be that uncommon.Unfortunately there are many "common" requirements that just couldn't be
met with XSL-FO 1.0 that will be addressed in future versions. I
understand that had the committee tried to add everything in the first
version, it would never have been released due to feature creep. The first
version was necessary to understand how it was going to be used.
