Attribute Definitions:

PredefinedType :

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

Formal Propositions:

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