  New properties of the quark correlator are found via equations of motion. As
a first result, approximate relations can be established among the "soft"
functions; one such relation may help in determining the quark transversity in
a nucleon. Secondly, the Q^2 dependence of the T-odd functions is deduced; the
result is compared to unpolarized Drell-Yan data. Lastly, important remarks are
made about the contributions to g_2(x).
