Session broker and custom conversion manager

Question

I'm having some problem using session broker and a custom conversion manager. I just moved from using single session to using a session broker in the sessions.xml. I'm using a custom conversion manager as shown in this tech. tips URL
http://www.oracle.com/technology/products/ias/toplink/technical/tips/customconversion/index.html
Here's my conversion manager set up code -
public class JpmiConversionManagerSetup extends SessionEventAdapter
* During the pre-login event the new MyConversionManager must be installed
* @see oracle.toplink.sessions.SessionEventAdapter#preLogin
* @param event
public void preLogin(SessionEvent event) {
ConversionManager cm= new JpmiConversionManager();
ConversionManager.setDefaultManager(cm);
event.getSession().getLogin().getPlatform().setConversionManager(cm);
My session broker manages 2 sessions. In sessions.xml for one session I have the <event-listener-class> entry where I need some conversion, another session I don't have any such entry as I don't need any conversion.
Now when I try to run a named query using session broker the conversion part blows up, throws a ConversionException. Any idea? Do I need to configure the session broker instead of session in the preLogin or anything like that?

I think sessions editor is not available in 10.1.3dp4 yet. So I have to write the sessions.xml by hand. But the parser throwing me an error saying that <session-broker> is not allowed in sessions.xml.
SessionLoaderExceptions:
org.xml.sax.SAXParseException: <Line 41, Column 18>: XML-24534: (Error) Element 'session-broker' not expected.
