      Description

      The property attribute of MEASURED is included to enable
      the function is_strictly_comparable to be evaluated - it provides
      a way of comparing any two Quantities which measure the same
      property, such as 'acceleration'', or even a basic property like
      'mass', where the literal units are different. However, this means
      that property must be provided for each instance of QUANTITY, and
      it is rarely known in legacy or feeder system data. It can be
      inferred if the units string is passed to a quantitative knowledge
      module, however, if we accept that this is required, then property
      is not needed anyway - it can be replaced by a function that
      determines if two unit strings measure the same property.
