        DESCRIPTION
               "An object using this data type represents a sensor
                precision range.
                
                An object of this type SHOULD be defined together with
                objects of type EntitySensorDataType and
                EntitySensorDataScale.  Together, associated objects of
                these three types are used to identify the semantics of an
                object of type EntitySensorValue.
                
                If an object of this type contains a value in the range 1 to
                9, it represents the number of decimal places in the
                fractional part of an associated EntitySensorValue fixed-
                point number.
                
                If an object of this type contains a value in the range -8
                to -1, it represents the number of accurate digits in the
                associated EntitySensorValue fixed-point number.
                
                The value zero indicates the associated EntitySensorValue
                object is not a fixed-point number.
                
                Agent implementors must choose a value for the associated
                EntitySensorPrecision object so that the precision and
                accuracy of the associated EntitySensorValue object is
                correctly indicated.
                
                For example, a physical entity representing a temperature
                sensor that can measure 0 degrees to 100 degrees C in 0.1
                degree increments, +/- 0.05 degrees, would have an
                EntitySensorPrecision value of '1', an EntitySensorDataScale
                value of 'units(9)', and an EntitySensorValue ranging from
                '0' to '1000'.  The EntitySensorValue would be interpreted
                as 'degrees C * 10'."

                The semantics of an object using this data type are

                indicates how many fractional digits are represented in the
                associated EntitySensorValue object.
                
                If the associated EntitySensorDataType object is equal to
                'percentRH(9)', then an object of this type MUST contain a
                number ranging from 0 to 100.
                
                If the associated EntitySensorDataType object is equal to

                ranging from -999,999,999 to +999,999,999.
                
                If the associated EntitySensorDataType object is equal to

                The value zero indicates:
                
                    - the sensor value is updated on demand (e.g.,
                      when polled by the agent for a get-request),
                    - the sensor value is updated when the sensor
                      value changes (event-driven),
                    - the agent does not know the update rate.
