We calculate the universal radiative QED corrections to polarized lepton scattering for general scattering cross sections in analytic form. The flavor non--singlet and singlet radiation functions are calculated to $O((\alpha {\rm L})^5)$. The resummation of the non--singlet and singlet contributions to the QED--anomalous dimensions $\propto(\alpha \ln^2(x))^k$ is performed to all orders. Numerical results are presented for the individual radiation functions. Applications to polarized deeply inelastic lepton--nucleon scattering are given.
