class Ifc4::IfcExternalInformation : public IfcUtil::IfcBaseEntity

The IfcExternalInformation identifies the external source (classification, document, or library), but not the particular items such as a dictionary entry, a classification notation, or a document reference within the external source

The IfcExternalInformation is an abstract supertype of all external information entities.
