Hi!

Thanks for your hints!

Yes, this seems to be the problem. Unfortunately, I can't think of an XSLT
processor that automatically reads in the entity files. How does XML
"know" about these files, by the way? AFAIK, these files are referenced in
the catalog files, which are only used by DSSSL processors, like jade or
openjade. Or am I wrong on this issue?

The xalan processing fails:

java org.apache.xalan.xslt.Process -in 
evaluation_textverarbeitungssysteme.xml -xsl
/opt/xml-root/xsl/docbook/fo/docbook.xsl -out
evaluation_textverarbeitungssysteme.fo

Thanks for any hints!
