  General topologically invariant microscopical expressions for quantum numbers
of particle-like solitons ("skyrmions") are derived for a class of (2+1)D
models. Skyrmions are either half-integer spin fermions with odd electric
charge or integer spin bosons with even charge. So they cannot be Anderson's
spinons or holons. General results are exemplified by a square lattice model
reminiscenting high-Tc models.
