Docbook stylesheets assign the IDs (that are referenced by the outline and the toc) for chapters etc. to the fo:page-sequence element. But FOP does support some functionality (fox:outline, fo:basic-link?, fo:page-number-citation) only for referenced fo:block elements. There are two possible solutions: 1. change/customize the stylesheets (assign id's only to fo:block), 2. patch/extend FOP. I have done 1. as an example for the chapter element. Changes would appear in fo/component.xsl (in the template that matches chapter) and in fo/titlepage.templates.xsl (I know this file is generated. For a clean solution template/titlepage.xsl have to be changed. Possible? Is it worth a test?). (Changes are documented at the end of this mail.) My questions are now: - What would be the right way: change docbook stylesheets or FOP? - What say the xsl-fo specs (I know: RTFSpec :-). Maybe someone else has done this before and can answer.) - If we/I would customize the stylesheets, would this cause side effects?
