Much more details and explanations in:
A. Dal Corso,
Projector augmented-wave method: application to relativistic
spin-density functional theory,
Phys. Rev. B 82, 075116 (2010).
Pseudopotentials with spin-orbit and other tests:
A. Dal Corso,
Pseudopotentials periodic table: from H to Pu,
Comp. Material Science 95, 337 (2014).

Its main approximations are related to the “pseudization” of the atomic wave functions, as in the scalar relativistic case, plus the neglect of the “small component” in the Dirac equation, plus other details that I don’t know exactly.
