I get a non conforming FO-file with current version of xsltproc from a
docbook-file. Older versions do the job like fop does it too. The following
document gives e more detailed report.

    <title>Problem with current xsltproc</title>
<section>
      <title>Introduction</title>
<para>I encountered a problem with the current version of xsltproc together
with docbook XML version 4.1.2 and docbook xslt package version 1.44 from
sourceforge. (Tried todays cvs too.)</para>
<para>If I use &lt;section&gt; recursive I ran into problems with the
created FO-file when processing with fop.

<title>worked realy fine</title>
<para>If I use an earlier version of xsltproc, fop runs without error.

produces a bad FO-file.
