XSL, glossary as child to part not working in FO

["Thomas, Ludger" <Ludger.Thomas@iese.fraunhofer.de>]

Hi all,
I have a question concerning the "glossary as child to part" discussion
recently.
http://sources.redhat.com/ml/docbook-apps/2004-q4/msg00078.html
http://sourceforge.net/tracker/?group_id=3D21935&atid=3D373747&func=3Dde
t=
ail&a
id=3D1046371

In my DocBook files I set up a structure like this ...
Part C
Part D
 appendix
   quandaset
 glossary
 index

When I transform this structure to FO (using the 1.68.1 Stylesheets and
XSLTPROC) the glossary element (fo:block) becomes a direct child of
fo:root which is of course not valid. Using glossary as a direct child
of book works fine. Any solutions?

Thanks and best wishes.
Ludger Thomas
