The IfcExtendedProperties is an abstract supertype of all extensible property collections that are applicable to certain characterized entities. Instantiable subtypes of IfcExtendedProperties assign the property collection to a particular characterized entity.
NOTE Extensible property collections are provided for materials and profiles.
Instantiable subtypes have a set of Properties, each providing property name, value and unit and other instance information, depending on the subtype of IfcProperty referenced.
HISTORY New entity in IFC4.
