[xep-support] Alternating body templates with XSL-FO

I have an XSL-FO question.


I am generating a book that may have hundreds of pages. For the general
chapters (not concerned with title pages, index, etc.) I need to be able to
alter body templates based on even and odd pages. I already understand how
to do this for the static content on the page (region before and region
after areas) but have been unable to do it for the body.



Does anyone know if it is possible to have a conditional page body depending
on whether or not the page is even or odd? I understand how to have
conditional page-before and page-after (static content) styles. But I also
want the body text (flow) to be formatted differently depending on whether
or not the page is even or odd.

Below you can see my attempt at this by creating "body-even" and "body-odd"
in the even and odd master sets. This attempt, however, just fills up all
the odd pages leaving the even pages blank. I think it might be possible
doing something similar to what I am doing, but I just don't have it quite
right. It would also be possible if, in my XSL, I could somehow say. "If
even" or "If odd" and then call the appropriate template.


Your input would be appreciated.
