docbook-slides: footnote in title ?

[Mathieu Malaterre <mathieu.malaterre@gmail.com>]

Hi there,

  Does anyone knows whether the following is valid:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE slides PUBLIC "-//Norman Walsh//DTD Slides XML V3.4.0//EN"
"http://docbook.sourceforge.net/release/slides/3.4.0/schema/dtd/slides-full.dtd";>
<slides>
  <foil>
  <title>My Title<footnote><para><ulink
url="http://www.example.com/"/></para></footnote></title>
  <para/>
  </foil>
</slides>

it makes fop crash with a java.lang.NullPointerException exception.

as a side note, the following is working nicely:

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE article PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"
"http://www.oasis-open.org/docbook/xml/4.5/docbookx.dtd";>
<article>
<section>
  <title>My Title<footnote><para><ulink
url="http://www.example.com/"/></para></footnote></title>
  <para/>
</section>
</article>
