olinking between PDFs using FOP

I’m following Bob Stayton’s book to implement
olinks to link between PDF files. However, the fragment identifiers (e.g.,
myotherbook.pdf#intro) aren’t recognized by FOP. I’m using FOP 0.93
and I’ve set the insert.olink.pdf.frag parameter to 1. It still doesn’t
work. When I click the olink, it opens the correct PDF file but doesn’t
scroll down to the referenced section (as described in http://www.sagehill.net/docbookxsl/OlinkPrintOutput.html#PdfLinkingSetup).

 

Can someone suggest another XSL-FO processor where olinking
between PDFs works properly? Is there any way I can make it work with FOP?
