It is shown that the magnitude of the current-quark mass m_f of the quark and antiquark inside the produced vector meson determines the onset of the asymptotic-q^2 power-law behavior of the cross section, and how correlated quark-exchanges are included to provide a complete picture of the diffractive electroproduction of light vector mesons applicable over all energies and photon momenta q^2.Talk given at ``Jefferson Lab Physics & Instrumentation with 6-12 GeV Beams'' June 1998. 4 pages RevTeX, 7 figuresNuclear TheoryHigh Energy Physics - Phenomenologytext
