The expiration model is just that when the Document goes away the urn:uuid is changed to no longer represent that chunk of data. The origin is something that at least in gecko we build on top of the URI, i.e. the URI itself doesn't contain any origin information. If you consider it to be part of the URI, then why wouldn't each urn:uuids already have an origin? / Jonas
