        Element types of 'allValuesFrom' and 'someValuesFrom' 
        are extended to DataRangeType.  In addition, 'hasValue' 
        element is added. 
      

        A content type of 'hasValue' element (data literal) may be 
        specified by using 'xsi:type' attribute, which is part 
        of the XML Schema instance namespace.  A literal type can 
        be either one of built-in non-list XML Schema datatypes.
