According to
http://www.w3.org/TR/2004/REC-xml-20040204/#sec-well-formed
the XML-declaration must not be preceeded by anything except a byte-order mark.
This is also explained in
http://www.w3.org/TR/2004/REC-xml-20040204/#sec-guessing.

The XML-declaration is not necessary, when the encoding is UTF-8, 
UTF-16 or US ASCII.
If there is no XML-declaration, an XML entity may start with white 
space characters, according to
http://www.w3.org/TR/2004/REC-xml-20040204/#NT-prolog.
