Summary
I review the CDP approach to DIS at low $x \cong Q^2/W^2 < 0.1$.
All essential experimental results can be theoretically obtained
model-independently, i.e. without a specific free-parameter-dependent
ansatz for the dipole cross section. The limits of color transparency
and saturation, in terms of the Compton-forward-scattering amplitude,
correspond to a two-channel versus a one-channel interaction of the
color dipole with the gluon field in the nucleon. The connection with
the pQCD-improved parton model is elaborated on. Compare also my
recent review talks arXiv: 1112.2885 and my presentation given at the
International Summer School of Subnuclear Physics 2012 (Erice, 23 June
-- 2 July 2012),
