Query: Next-to-leading Order Evolution of Transversity Distributions and
  Soffer's Inequality   We present a calculation of the two-loop splitting functions for the
evolution of the twist-2 `transversity' parton densities of transversely
polarized nucleons. We study the implications of our results for Soffer's
inequality for the case of valence quark densities.
