Query: Comment on ``Analysis of Floquet formulation of time-dependent
  density-functional theory'' [Chem. Phys. Lett. {\bf 433} (2006), 204]   We discuss the relationship between modern time-dependent density functional
theory and earlier time-periodic versions, and why the criticisms in a recent
paper (Chem. Phys. Lett. {\bf 433} (2006) 204) of our earlier analysis (Chem.
Phys. Lett. {\bf 359} (2002) 237) are incorrect.
