XSL-FO and PDFMark

Hello everybody.

Maybe it’s a newbie question but I’m looking for a possibility to
incorporate PDFMark into a PDF file generated with FOP or any other
XSL-FO2PDF processor.
Does anybody have experience with that? Currently I’m working on a XML
schema / XSL stylesheet combination that does a proper PDFMark coding from
normal XML elements. Therefore I could incorporate Cdata sections with the
correct PDFMark into a resulting file.
But is this possible at all?

Thx for your help,

Jürgen
