I'd be wary of any default beyond string = string; anything more implies a fairly complete list of URIs that might be encountered, as well as well-understood canonicalisation for each of them; IMHO we don't have either. What would be very useful would be a canonicalisation framework along the lines that Tim suggested, to give spec writers something to refer to. Cheers, -- Mark Nottingham http://www.mnot.net/
