well, I have found the problem of why there was being inserted two metadata 
elements with the
same ID, and I now generate a more nice looking xml, in any case I don't 
figure out why it cannot be converted to DOM:

<?xml version="1.0" encoding="UTF-8"?>
<nmwg:message xmlns:nmwg="http://ggf.org/ns/nmwg/base/2.0/"; 
id="resultCodeMessage">
   <nmwg:metadata id="resultCodeMetadata">
      <nmwg:eventType>error.common.parse_error</nmwg:eventType>
   </nmwg:metadata>
   <nmwg:data id="resultDescriptionData_for_resultCodeMetadata" 
metadataIdRef="resultCodeMetadata">
      <nmwg:datum value="Cannot convert Message to DOM" />
   </nmwg:data>
</nmwg:message>

The XML file is

<nmwg:message id="localhost.localdomain.-5ae93b59:10d3a9f2382:-7e75"
    type="TOPSDownloadDBResponse" 
xmlns:nmwg="http://ggf.org/ns/nmwg/base/2.0/";>
