The StatsAreaType defines a StatsNumericalBaseType with an optional areaUnit attribute that identifies the unit being used by its unit name. If no value for the attribute is given in an instance file when an area value is given, the unit type is the primary area unit specified in the PrimaryUnits element of a FileUnits element, if there is a FileUnits element, and square meters if not.
The optional areaUnit attribute defines the unit used by StatsAreaType.
