  A phenomenological renormalization scheme for hadronic diffraction is
proposed, which achieves unitarization without the need for "screening
corrections". Predictions for diffractive photoproduction cross sections at
HERA are presented and compared with experimental results. A new interpretation
of hard and deep inelastic diffractive data emerges, in which the momentum sum
rule is obeyed by the constituents of a pomeron described as a mixture of quark
and gluon color singlets in a ratio dictated by asymptopia.
