The new version of the HTTP spec, 2616bis, should definitely
drop the iso-8859-1 default, but NOT in favor of "unknown text is ASCII".
It should just say that there is no default.
There is a big difference between these two, especially
for document formats that contain internal 'charset' information.
A default of US-ASCII makes document-internal 'charset' information
useless (because the external information wins). No default means
that the recipient will look at the internal information.

One reason for the problems with text/xml was that the
original MIME default of US-ASCII was enforced. This made
it impossible to serve XML documents with internal 'charset'
information only as text/xml.
