  On incorporating special relativity theory into an extended equivalence
principle, post-Newtonian gravitational phenomena beyond that originally
predicted by Einstein are predicted (required), such as geodetic and
gravitomagnetic precessions of local inertial frames, and precession of
Mercury's orbital perihelion. Why were not these phenomena predicted in the
years 1907-1911? The unique 1/c^2 order dynamical equations for clock rates and
motion of both bodies and light in local gravity are derived which guarantee
fulfillment of the special relativistic equivalence principle.
