I think that when speaking about architectural issues, malfunctions can be kept out of scope, with the clear understanding that if/when things break, strange thigns happen -- though strange happenings would certainly be an indication that something is broken. Perhaps the above could be modified to "if any URI ever returns different octet streams then one should be licensed to conclude that that URI does *not* denote a Representation, or that the server is malfunctioning in some manner. > > The only way I can see around this is, if you want to preserve the > claim, is by appeal to some notion of a legitimate or successful > derferencing, ... but that has its own problems. > > Dan > > ps. I like the clock example. Simple but with nice complexity (eg. > language negotiated content too). Agreed. Cheers, Patrick
