  // common block attribute. This is the case where such a block attribute
  // may result from a particles-to-cells interpolation process. Thus those
  // blocks with particles (e.g., the reference one with the fewest cells)
  // contain it as a block attribute, whereas others without particles just
  // do not contain this block attribute.
