However, OWL certainly does this (and not only for explicit subtypes). XML Schema mostly does this too. So, I'd say you're covered. > Can I read more about this anywhere? Well, I can't seem to connect to daml.org at the moment, but there is a section on IO typing toward the end. An appendix, I think. Disclaimer: I wrote that section, but under a bit of duress :) Cheers. Bijan.
