And when I said 'under' I meant nested bookmarks.
The problem I am having is that since the element 'task' can repeat
for a chapter, I am unable to generate the bookmark internal
destination ids to be unique. Since FOP does not support XSLT 1.0 (
and I restricted to this product), I am not able to use the xslt 2.0
for-each-group to be able to group the tasks. I have to use keys to
group them. Is there any other better way of doing this?
"Better"? No. In my class and in my book I point out there are
three ways to do grouping in XSLT 1.0: by axes (best for adjacent
grouping), by keys (best for full-document grouping) and by variables
(best for sub-document grouping and multiple-document grouping). I
describe these approaches starting on page 411 of my XSLT book that
can be downloaded in its entirety in a "try and buy" format in either
A4 or US-letter page sizes here:
http://www.CraneSoftwrights.com/training/#ptux
BTW, I describe XSL-FO bookmarks in chapter 9 section 1 of my XSL-FO book here:
http://www.CraneSoftwrights.com/training/#pfux
If you only have one set of tasks and you need to group them by
chapter, then key-based grouping is the best for XSLT 1.0.
I hope the example below helps.
