No, it isn't, see <http://www.w3.org/TR/REC-xml/#IDAY3EU>: "Unless an
encoding is determined by a higher-level protocol, it is also a fatal
error if an XML entity contains no encoding declaration and its content
is not legal UTF-8 or UTF-16." This rule is so self-evident.

That's no proof. AFAIK, Opera _never_ uses ISO-8859-1 internally, at
least on the Windows platform. It assumes Windows-1252 even for
<http://schneegans.de/sv/test-cases/?case=control-characters> and decodes
0x80 to U+20AC, not U+0080.
All free men, wherever they may live, are citizens of Denmark. And
therefore, as a free man, I take pride in the words "Jeg er dansker!"
