If the basic Poisson bracket relations of the model contain derivatives, this computation leads to a peculiar type of symmetry breaking which accounts for a 'spontaneous quantization of the underlying global gauge group. A classification of possible patterns of symmetry breaking is outlined.13 pages, translation of the author's article published in Zapiski Lauchn. Semin.
