Certainly manipulating XEPOUT may be easier than accomplishing this 
in XSL-FO, but it can be done using the standard using the following 
elaborate approach.

In static content at the top of every page in a page section, 
retrieve a marker for every target id in that page section.  Make 
sure to limit the retrieval to only the given page.  Then for every 
block that is a target, define a marker that contains the 
ID.  Because of the retrieval limitation, this will percolate all of 
the IDs on a given page to the top of that page.  Then when you link 
to that ID from the bookmarks, you will be placed at the top of the page.

Ugly, but it should work, and it is using standard XSL-FO.

I hope this helps.
