Okay, but with a flourish I can produce the URI zip://atm.example.org/06902 or, worse, zip:06902 but just because these now have URIs does not lessen in any way their proprietary nature, and the second one is probably not dereferencable either.

Under what PP> circumstances is a proprietary address space an advantage? Its hard to justify, I agree. It doesn't get easier to justify by giving them URIs, though. To really help, they have to be dereferencable, otherwise they are mere syntactic fluff. Although I agree that anonymous resources without URIs are a problem, particularly for linking to them or into them. The results of client-side XSL-T processing are a case in point. -- Chris mailto:chris@w3.orgReceived on Monday, 18 March 2002 20:18:02 GMT
