But there's the snag: in text/xml documents, a missing charset parameter does not mean "Charset unspecified"; it means "Charset specified as US-ASCII". There is no way to fail to specify a charset in text/* documents, and rightly so, because text without a charset is uninterpretable. In SGML terms, omitting the charset in text/* documents is a mere minimization, whereas in application/* documents it is a true #IMPLIED. -- John Cowan http://www.ccil.org/~cowan cowan@c...
