Note on: "Domain wall universe in the Einstein--Born--Infeld theory"   Phys. Lett. B 679 (2009) 160
  The interaction between bulk and dynamic domain wall in the presence of a linear / non-linear electromagnetism make energy density, tension and pressure on the wall all variables, depending on the wall position. In [1] this fact seems to be ignored.
