Attribute Definitions:

PredefinedType : Kind of tendon anchor.

Formal Propositions:

CorrectPredefinedType : Either the PredefinedType attribute is unset (e.g. because an IfcTendonAnchorType is associated), or the inherited attribute ObjectType shall be provided, if the PredefinedType is set to USERDEFINED.
CorrectTypeAssigned : If this occurrence is defined by a type object, the latter has to be an IfcTendonAnchorType.
