  The long-distance electromagnetic radiative corrections to tau- -> pi- pi0 nu
are re-evaluated. A meson dominance model is used to describe the emission of
real photons in this decay. Results obtained for the hadronic spectrum and the
decay rate in photon inclusive reactions are compared with previous
calculations based on the chiral resonance theory. Independent tests in tau ->
pi pi nu gamma that can help to validate the predictions of one of the two
models are briefly discussed.
