Since we dropped QCRs, OWL DL is only SHION(D+) (the (D+) referring to datatypes), so we don't cover QCRs. Having said that, I am no more keen on a 3-4 month delay than you are. As an alternative, might it be possible to gather together sensible proposals from the LC process with a view to an early release of OWL 1.01, or some such? Hopefully we can discuss this issue on Thursday. Ian > This means that we should be able to develop an > idiom within our current language to handle them (even if it means > creating extra classes).
