Another part of the definition of Accept: is that the MIME types
accepted by registered client helpers should be listed.

We have client helpers that can accept vector graphics. If they are
not present the server can send a GIF.

The Accept: field is currently useless in most browsers because it
does not specify the formats which can be used.

A good definition would be:-

  The native presentable formats of the browser

  The registered formats of helpers

Preference information can be added for format negotiation purposes.
Much could be expressed by a simple linear ordering -- list what
you prefer first.
