      The NewsML-G2 XML Schema includes
      l-Power.xsd) multiple Extension Points which are defined as
      <xs:any namespace="##other" processContents="lax" minOccurs="0"
      <xs:documentation>Extension point for provider-defined
      properties from other namespaces</xs:documentation>

      Which means:
      - their purpose is to hold additional provider specific properties
      - the names of these additional properties must be from another namespace =
      not the nar: namespace

      Typically these Extension Points are placed as last child of elements which
      act as wrapper of properties, e.g. rightsInfo, itemMeta, contentMeta,
