Local gauge models predicting their own superselection rules

By considering local $\mathrm{SO}(2)$ or $\mathrm U(1)$ transformations of two-component Boson field in two-dimensional space-time we construct certain non-vacuum representations of the canonical commutation relations between which superselection rules operate.
The models suggest that a widening of the axioms of Haag, Doplicher and Roberts, is desirable in certain gauge models.
