[1] is a good point, and one that I don't remember a good answer to. I have
a different take on it.

You seem to say that "oneOf" ought be removed from OWL-DL in order to give
OWL-DL the properties that we've been told it will have -- fast (somewhat)
efficient reasoning. Either "oneOf" does or doesn't belong in OWL-DL, but I
guess I've always thought OWL-Lite to have a significantly different
constituency than OWL-DL.

Right, ok, but *you* are an OWL-DL person (sorry to pigeonhole you, but
let's be totally clear about this). I am looking to the OWL-Lite folks for
this answer.

People, if *we* can't be clear on this layering/relationship issue between
our set of languages, the rest of the world is going to get terribly
confused -- this could turn OWL into an Ostrich.
