Having the XML prologue as the first line will make the XML valid, but 
it will also make IE6 render the page in quirks mode instead of in 
standards mode. The usual advice in this case is to remove the XML 
prologue altogether because it is not required for XHTML (the encoding 
is sent via the HTTP header anyway).

So -1.
