Problem generating docbooks for calligraplan

[Freek de Kruijf]

When generating docbooks for calligraplan I get the following error message, 
which is repeated an additional 3 times:
A         nl/docs/calligraplan/calligraplan/portfolio/index.docbook
index.docbook:69: element sect1: validity error : Element sect1 content does

&scheduling; is defined as:

Generating this docbook shows no error.
the file .../documentation/calligraplan/calligraplan/portfolio/
schedulingview.docbook shows 4 sect1 sections. The last 2 are virtually empty; 
it is work in progress!

Something wrong with syntax of a sect1 section there?
