Comment on "Accurate relativistic effective potentials for the sixth-row   main group elements" [J.Chem.Phys. 107, 9975 (1997)]
  Critical remarks in respect to the Generalized Relativistic Effective Core Potential in the recent article of S.A.Wildman at al. are discussed and shown to be incorrect.
