EXPRESS Specification:

ENTITY IfcFilter
SUBTYPE OF (IfcFlowTreatmentDevice);
PredefinedType : OPTIONAL IfcStrippedOptional;
WHERE
CorrectPredefinedType : NOT(EXISTS(PredefinedType)) OR (PredefinedType <> IfcFilterTypeEnum.USERDEFINED) OR ((PredefinedType = IfcFilterTypeEnum.USERDEFINED) AND EXISTS (SELF\IfcObject.ObjectType));

END_ENTITY;

Formal Propositions:

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