If you download the free excerpt of our XSL-FO book from our web site cited
below, this excerpt was produced using XEP and contains a tremendous number
of local hyperlinks, mostly in the back-of-the-book index, but also
throughout the text.

One of the XSL-FO objects you produce for each of these will need a unique
identifier. The production of areas from these objects will place these
unique identifiers in the area tree. An XSL-FO processor links to target
ids in the area tree (not to target ids in the formatting object tree).

Good! Then use that identifier in your formatting object that produces
areas in your area tree. I find when aggregating XML instances that I
cannot use the naked identifier, that I have to use generate-id() to ensure
uniqueness, but from what you say this is not the case for you.
Where you make the reference, use the <basic-link> construct with the
internal-destination= property being the identifier to which you want the
user to jump. Then, the areas created by your <basic-link> become the
"hot" areas for operator interaction: where they click.

You will use <basic-link> with internal-destination= the @linkend attribute.

You will use <block> or <inline> or whatever you need for that construct,
with the id= being the @id value.
><link linkend="EGMG_ensemble_management_portal">Ensemble Management
>Portal</link>
><chapter id="EGMG_ensemble_management_portal"> ... </chapter>
This is what I do for *all* my internal links in my book
excerpt. Actually, you will find at the bottom of every page except the
title page 28 internal hyperlinks for access to the table of contents and
portions of the index. Also, we have hyperlinked the section numbers of
the XSL-FO specification out to the web document at the W3C by using
external-destination= ... this allows readers to use our books to jump
around the W3C document. Try it out from any of the section numbers listed
in the property section.
I hope this helps.
