Formal Propositions:

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