thanks for clarifying, but let me make sure that I understand what that 
means:

mime-type=text/xml but no charset

AND

<?xml encoding="UTF-8"?>

means encoding="us-ascii", right?

But in the case of mime-type=application/xml the XML declaration is 
authoritative also when the charset header is missing?

Or otherwise can you give some examples to really understand what 
sentence below actually means?

Thanks
