Differential (e,e'pp) measurements are presently recognized as a way of studying short-range correlations in finite nuclei. The ((e) over right arrow,e'(p) over right arrow p) and ((e) over right arrow,e'(p) over right arrow n) differential cross section and polarization observables are studied in a microscopic model that accounts for the short-range correlations, outgoing-nucleon distortions, meson-exchange and Delta-isobar currents. It is pointed out that polarization observables represent an attractive alternative for absolute electronuclear two-nucleon knockout measurements. In the polarization transfer P-t' for ((e) over right arrow,e'(p) over right arrow p), the effect of central short-range correlations is predicted to be large while at the same time the final-state interaction effects are small.
