  We discuss properties of statistical QCD relevant in Fermi phase space model
analysis of strange hadron production experimental data. We argue that the
analysis results interpreted using established statistical QCD properties are
demonstrating formation of the color deconfined state of matter in relativistic
heavy ion collisions at highest CERN-SPS energies and at BNL-RHIC, comprising
deconfined matter composed of nearly massless quarks and gluons, in statistical
equilibrium.
