Similarly to the bosonic case we arrive at field operators which are indeed operators and not operator valued distributions. Observables such as four-momentum and charge can be defined without any need of normal ordering.continuation of quant-ph/0211009 (and not 0211099!), revtex, 8 pages, submitted to Phys. Lett.
