    "abstract": "In quant-ph/0406139, we have introduced in a very general setting the new\nclass of quantum states, density source-operator states, satisfying any\nclassical CHSH-form inequality, and shown that any separable state belongs to\nthis class. In the present paper, we prove that the Werner nonseparable state\nalso belongs to the class of density source-operator states. Moreover, for any\ndimension d\u003e2, the Werner state is in such a subclass of this class where each\ndensity source-operator state satisfies also the perfect correlation form of\nthe original Bell inequality regardless of whether or not the Bell perfect\ncorrelation restriction is fulfilled. The latter earlier unknown property of\nthe Werner state can be verified experimentally.",
