If you know the text is XML, then you can determine the charset by
Appendix F methods; but if "text/xml" is just "text/*" to you, then
you must be able to rely on the (possibly minimized) charset
parameter in the media type, because if there is no charset,
the text/* is, as I said, uninterpretable.

I meant that if you are processing a MIME document, as long as you
know its major type is "text", you can always determine the charset.
There is either an explicit charset parameter, or the implicit
charset of either "US-ASCII" or "ISO-8859-1" depending on the
underlying transport protocol.
