Abstract
Extended BRS symmetry is used to prove gauge independence of the fermion renormalization constant in on-shell QED renormalization schemes. A necessary condition for gauge independence of in on-shell QCD renormalization schemes is formulated. Satisfying this necessary condition appears to be problematic at the three-loop level in QCD.
