  The failure of property composition in the modal interpretation calls for explanation. It may be tempting to postulate that the properties that a system (e.g. the L-particle) has, as a separated system, are the same as the properties that it has as a subsystem of composite systems. But, as Bacciagaluppi (1995) and Clifton (1996a) have shown, such property assignment will be inconsistent: It will be subject to a Kochen and Specker-type contradiction. Furthermore, as Vermaas (1997) demonstrates, the properties of composite systems and the properties of their subsystems cannot be correlated (in ways compatible with the Born rule).
