title: Unmarshalling root element returns null for sub elements
body: <p>I am dealing with one weird issue from couple of days.  Issue is  with unmarshalling while getting values for root element.  All elements returned as null.</p>
  
  <p><b>Scenario:</b>  I have 2 XSDs with complex elements and with different namespaces  referred and imported in 3rd XSD.  JAXB files are generated in different packages.</p>
  
  <p>If I use only simple XSD everything goes well. But referring sub elements from different XSDs returns null for sub elements after unmarshalling.</p>
