Hi Mike -- the problem is format negotiation. I have services that can
give better interaction if an appropriate helper is installed, but can
still give useful functionality if not. So I need to know at the server
whether the helper application is registered or not. That was the purpose
of the Accept field -- not to say "I accept *.* because I can dump it in
a file regardless of whether that file is usable or not."

It's like a lot of HTML/HTTP, what was intended has never been defined,
and I guess Roy Fielding's work on defining HTTP is where we should look for
clarification. The debate on www-talk at least demonstrates that there
are 2 schools of thought (if not more!).
