      Upon re-opening the DMN file it fails to render the file in the DMN editor, and the following changes to the original xml file can be observed:

      a) new default xmlns attribute in definitions element has been added to the dmn file:
      xmlns="http://www.trisotech.com/definitions/_4e0f0b70-d31c-471c-bd52-5ca709ed362b"
      b) "tns:" has been changed to "tns."
