EXPRESS Specification:

ENTITY IfcPump
SUBTYPE OF (IfcFlowMovingDevice);
PredefinedType : OPTIONAL IfcStrippedOptional;
WHERE
CorrectPredefinedType : NOT(EXISTS(PredefinedType)) OR (PredefinedType <> IfcPumpTypeEnum.USERDEFINED) OR ((PredefinedType = IfcPumpTypeEnum.USERDEFINED) AND EXISTS (SELF\IfcObject.ObjectType));
CorrectTypeAssigned : (SIZEOF(IsTypedBy) = 0) OR ('IFCHVACDOMAIN.IFCPUMPTYPE' IN TYPEOF(SELF\IfcObject.IsTypedBy[1].RelatingType));
END_ENTITY;

Formal Propositions:

CorrectPredefinedType : Either the PredefinedType attribute is unset (e.g. because an IfcPumpType is associated), or the inherited attribute ObjectType shall be provided, if the PredefinedType is set to USERDEFINED.
CorrectTypeAssigned : Either there is no pump type object associated, i.e. the IsTypedBy inverse relationship is not provided, or the associated type object has to be of type IfcPumpType.
