Attribute Definitions:

PredefinedType :

Identifies the predefined types of cable fitting from which the type required may be set.

Formal Propositions:

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