        `durationType` -
      Returns:
        normalized date representation
      Throws:
        `SchemaDateTimeException` - Invalid lexical representation

    - #### compareDates

          protected short compareDates(org.apache.xerces.impl.dv.xs.AbstractDateTimeDV.DateTimeData date1,

                                       boolean strict)

      Compares 2 given durations. (refer to W3C Schema Datatypes "3.2.6 duration")
      Overrides:
        `compareDates` in class `AbstractDateTimeDV`
      Parameters:
