++ I think the original approach fits very well with content
++ negotiation. The attribute type="text/html" is indeed a content
++ negotiation, since the client requests a piece of data in
++ text/html format. If the server couldn't deliver it in the
++ requested format it shouldn't deliver anything.

But that's just _against_ content negotiation. With content
negotiation, the client tells the server which types it
can accept, or prefers to have. What's the point of telling the
client to ask for which type? Then there is nothing left
to negotiate.
