The quantum field theoretic treatment of inclusive deep--inelastic diffractive scattering given in a previous paper \citeBGR2006 is discussed in detail using an equivalent formulation with the aim to derive a representation suitable for data analysis. We consider the off-cone twist--2 light-cone operators to derive the target mass and finite t corrections to diffractive deep--inelastic scattering and deep--inelastic scattering. The corrections turn out to be at most proportional to x |t|/Q2, x M2/Q2, x = x\rm BJ \rm or x_\PP, which suggests an expansion in these parameters. Their contribution varies in size considering diffractive scattering or meson--exchange processes. Relations between different kinematic amplitudes which are determined by one and the same diffractive GPD or its moments are derived. In the limit t, M2 → 0 one obtains the results of \citeBlumlein:2001xf and \citeBlumlein:2002fw.
