That's what the How is this in scope for discussion _in the HTTP spec._? People (not user agents, note) use 200 responses for a huge range of interesting, powerful, innovative things. We don't look in the HTTP spec. to find a discussion of them. > "If the user agent is not satisfied by the initial response > representation, it can perform a GET request on one or more of the > alternative resources, selected based on metadata included in the > list, to obtain a different form of representation for that > response.

"based on metadata included in the list"! That's a specific reference to a 300 response. There is no "list" in a 200 response, not that a user agent can detect anyway. And, as I said in the last message, I'm not aware of _any_ user agent that does _anything_ specific to 300 responses. ht -- Henry S.
