Buggy source:

Fixed version (ground truth):

    }
 else {
      value=xmlCompositeDirectCollectionMapping.getValueConverter().convertObjectValueToDataValue(value,session);
    }
  }
  XMLField xmlField=(XMLField)xmlCompositeDirectCollectionMapping.getField();
  QName schemaType=getSchemaType(xmlField,value,session);
  String stringValue=getValueToWrite(schemaType,value,(XMLConversionManager)session.getDatasourcePlatform().getConversionManager(),namespaceResolver);

    marshalRecord.openStartElement(xPathFragment,namespaceResolver);
    XPathFragment nextFragment=xPathFragment.getNextFragment();
    if (nextFragment.isAttribute()) {
