[UPDATE: Meanwhile, FOP-1.0 has been released, which fixes the bug that informed this post. The workaround described below thus is only relevant for users of FOP versions 0.92 to 0.95. For the happiest FOPping experience, stop reading here and grab your copy of FOP-1.0!]

During the past couple of years, I’ve gathered some experience working with XML and related standards (XSLT, XSL-FO, XQuery). Part of our professional document production chain involves rendering PDF output from XML sources. I’ve grown into a big fan of Apache’s open source FOP processor since its now ancient version 0.20.5. Although the FOP code has been substantially revised and improved long since, the versions up to version 0.95 were haunted by one serious bug, which kept me from switching to an up-to-date version of FOP: footnotes inside lists or table cells got swallowed in PDF output.
On the other hand, FOP’s XSL-FO compliance rate has risen substantially in the recent versions, prompting me to find a way of dealing with this nasty show-stopper. Of course, I hope the FOP developers will be able to resolve this issue soon. In the mean time, I think I’ve found a way of circumventing (or at least alleviating) the problem (at stylesheet level; not at Java code level). Moreover, I think this approach might help other users as well, and other users might help improving this approach where it doesn’t.
