Yeah, I appreciate that concern. Everyone keeps telling me that this seems
like a problem in principle; apparently we're the only ones who built it
*as a real thing* and *in practice* it's not a problem at all. Our
customers don't find it in the least bit confusing. In fact, as we
originally said, most people who wanted OWL always wanted closed world
semantics anyway, so giving it to them is a big win.

Oh well. :>

Cheers,
Kendall
