I stumbled onto a technote about the interoperablility between the way XML is serialized by the BOXMLSerializer and the  format expected by JMSDataBindingImplXML. This is a concern if you serialize data from a business object and then put that data into a JMS Text message and choose ‘Text Message with DataObject Binding’ in the export.

Basically, they say to use the element (xsd:element name=”x”) declaration instead of the type (xsd:type name=’x’).
