FOP or stylesheet bug?

Hello All,

I have a nice document setup using xincludes and profiling. For some
reason I cannot produce pdf with fop bu I can produce html directly:

xmllint --xinclude test.xml > resolved.xml

xsltproc --output test.fo --stringparam profile.os "linux"
/usr/share/sgml/docbook/docbook-xsl-1.62.4/fo/profile-docbook.xsl
resolved.xml
Making portrait pages on A4 paper (210mmx297mm)
--produces test.fo--

xsltproc --output test.html --stringparam profile.os "linux"
/usr/share/sgml/docbook/docbook-xsl-1.62.4/html/profile-docbook.xsl
resolved.xml
--produces a fine test.html--

fop -fo test.fo -pdf test.pdf
[ERROR] file:/home/maarten/test.fo:2:38276 page-sequence must be child
of root, not fo:flow

I have seen this error in the postings of 2001, then it was a stylesheet
bug. Anyone a hint?

Kind regards,
