Specific choices of the parameters give rise to an $[SU(2)\\otimes SU(2)]^3$ symmetry. This symmetry can be obtained either {\\it \\'a la} Georgi, with all states in the spectrum remaining massless, or in a new realization, implying decoupling of the pseudoscalar bosons from degenerate vector and axial-vector mesons. This second possibility, when minimally coupled with $SU(2)\\otimes U(1)$ electroweak gauge vector bosons, seems particularly appealing.
