Two more issues came to mind here--

a.) My logic above is also relevant for fo:basic-link.

b.) My logic above of using both internal-destination
and external-destination together nevertheless appears
wrong for both fo:basic-link and fo:bookmark.

For external bookmarks, with the external-destination
referencing the other document, it does not appear
that the internal-destination property could be an
idref pointing to the location within the external
document, because that already-created external
document is not being generated via the XSL process.
Instead, it would need to be an internal identifier in
the external document's format.  (A PDF destination
identifier in the case of PDF.)  So the SG would
appear to need another property for external bookmarks
(and fo:basic-link), say, target-internal-destination
or similar, instead of using internal-destination.  

I am unsure, however, if the SG would be willing to
expand the spec to have a target-internal-destination
at this time, and for that reason might recommend
removing external-destination as an applicable
property for fo:bookmark in XSL 1.1 as an alternative.
 (Unless it can be considered acceptable in 1.1 to
have external bookmarks just bring up the document
without going to a specific page within it.)  External
bookmarks perhaps are best for future XSL spec
releases.

Thanks,
Glen
