schemalocation entry in XML created by castor created sources?

[Ulf Heyder]

I use castor-0.9.5 with xerces-2.4.0 to automatically generate classes
from XSDs via source generator and un-/marshall JAVA objects to/from
XML files.

My question is how to tell the castor source generator to create the
classes in a way that while marshalling they will create a
schemaLocation entry in the opening root tag:

<?xml version="1.0" encoding="UTF-8"?>
<liste
xmlns="http://www.test.de/test"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.test.de/test liste.xsd">
