Why? If people are still using text/xml for example you really want them 
to use the HTTP Content-Type header. Otherwise its US-ASCII.

Where did you read that in the XML specification? You can always specify 
encoding using the 'charset' parameter. That it is not recommended 
because "webarch" things documents should be self-describing doesn't 
matter. Also note that when the document is served using text/xml they 
could use UTF-8 but it wouldn't work.
