  We consider the polarization of Lambda + Lambda-bar baryons produced in
polarized Deep Inelastic Scattering at leading order, with various spin
configurations: longitudinally polarized leptons and unpolarized nucleon;
unpolarized leptons and longitudinally or transversely polarized nucleons;
longitudinally polarized leptons and nucleons. We show how the different
results in the different cases are related to different aspects of the
elementary dynamics and to the spin properties of the distribution and
fragmentation functions and show how a combined analysis might give useful
information. We give numerical results according to several sets of polarized
fragmentation functions recently proposed.
