12. In this simple model the singularity is only a coordinate singularity in the continuum theory, but one can consider more elaborate models where one deals in the same fashion with a real singularity.
13. The lack of constraints may lead to a construction of a theory that is renormalizable perturbatively, see for instance M. Kirchbach and D. V. Ahluwalia, Phys. Lett. B529, 124 (2002); Mod. Phys. Lett. A16, 1377 (2001).
