  We discuss the handbag approximation to exclusive deep virtual Compton
scattering. After defining the kinematical region where this approximation can
be valid, we propose tests for its relevance in planned electroproduction
experiments, e + p -> e + p + gamma. We focus on scaling laws in the cross
section, and the distribution in the angle between the lepton and hadron
planes, which contains valuable information on the angular momentum structure
of the Compton process. We advocate to measure weighted cross sections, which
make use of the data in the full range of this angle and do not require very
high event statistics.
