  I argue that quantum optical experiments that purport to refute Bohr's
principle of complementarity (BPC) fail in their aim. Some of these experiments
try to refute complementarity by refuting the so called particle-wave duality
relations, which evolved from the Wootters-Zureck reformulation of BPC (WZPC).
I therefore consider it important for my forgoing arguments to first recall the
essential tenets of BPC, and to clearly separate BPC from WZPC, which I will
argue is a direct contradiction of BPC. This leads to a need to consider the
meaning of particle-wave duality relations and to question their fundamental
status. I further argue (albeit, in opposition to BPC) that particle and wave
complementary concepts are on a different footing than other pairs of
complementary concepts.
