An IfcApproval represents information about approval processes such as for a plan, a design, a proposal, or a change order in a construction or facilities management project. IfcApproval is referenced by IfcRelAssociatesApproval in IfcControlExtension schema, and thereby can be related to all subtypes of IfcRoot. An approval may also be given to resource objects using IfcResourceApprovalRelationship
HISTORY New entity in IFC2.0
IFC4 CHANGE Attributes Identifier and Name made optional, where rule added to require at least one of them being asserted. Inverse attributes ApprovedObjects, ApprovedResources and HasExternalReferences added. Inverse attribute Properties deleted (more general relationship via inverse ApprovedResources to be used instead).
