The MeasuredSpeedValueType is an MeasuredDecimalType with an optional speedUnit attribute that identifies the unit being used by its UnitName. If no value for the attribute is given in an instance file when a speed value is given, the unit type is the SpeedUnit specified in the PrimaryUnits element of a FileUnits element, if that specification exists, and meters per second if not.
The optional speedUnit attribute defines the UnitName for the MeasuredSpeedValueType.
