Hi Anders,

This is an empty book, and your stylesheets probably generate an empty
Table of Contents for it. That's a fo:page-sequence with some
fo:static-content children and a fo:flow. In your case the fo:flow
will be empty, because there are no chapters to list. An empty fo:flow
is invalid however, and that's what the error message tells you:

> org.apache.fop.fo.ValidationException: Error(Unknown location):
> fo:flow is missing child elements.
> Required Content Model: marker* (%block;)+

The same thing happens if you generate e.g. an <article> with <para>s
but without <section>s, even though it's legal DocBook XML.
