  We present a model to calculate cross sections for electroinduced two-nucleon
emission from finite nuclei. Short-range correlations in the wave functions and
meson-exchange contributions to the photoabsorption process are implemented.
Effects of the short-range correlations are studied with the aid of a
perturbation expansion method with various choices of the Jastrow correlation
function. The model is used to investigate the relative importance of the
different reaction mechanisms contributing to the A(e,e$'$pn) and A(e,e$'$pp)
process. Representative examples for the target nuclei $^{12}$C and $^{16}$O
and for kinematical conditions accessible with contemporary high-duty cycle
electron accelerators are presented. A procedure is outlined to calculate the
two-nucleon knockout contribution to the semi-exclusive (e,e$'$p) cross
section. Using this technique we investigate in how far semi-exclusive
(e,e$'$p) reactions can be used to detect high-momentum components in the
nuclear spectral function.
