N2 - The causality and/or the energy-momentum conservation constraints on the amplitudes of high energy processes are generalized to QCD. The constraints imply that the energetic parton may experience at most one inelastic collision (an arbitrary number of elastic collisions) and that the number of the constituents in the light cone wave function of the projectile is increasing with the collision energy and the atomic number.
