Selecting IfcMeasureWithUnit allows the specification of both the
actual figure for the value together with the currency (for a cost value) or an
environmental measurement unit (in the case of an environmental impact value)
in which the value is represented.
Selecting IfcMonetaryMeasure allows the specification only of the
value, the currency being as set by the global context
Selecting IfcRatioMeasure assumes that the amount is a percentage
or other REAL number. Note that if the amount is normally specified as -20%,
then this figure will need to be converted to a multiplier of 0.8
