  Quantum properties of topological Yang-Mills theory in (anti-)self-dual
Landau gauge were recently investigated by the authors. We extend the analysis
of renormalizability for two generalized classes of gauges; each of them
depending on one gauge parameter. The (anti-)self-dual Landau gauge is
recovered at the vanishing of each gauge parameter. The theory shows itself to
be renormalizable in these classes of gauges. Moreover, we discuss the
ambiguity on the choice of the renormalization factors (which is not present in
usual Yang-Mills theories) and argue a possible origin of such ambiguity.
