is the encoding directive case sensitive

[Andy Fish]

hi,

is there any difference between these two declarations

<?xml version="1.0" encoding="UTF-8"?>
<?xml version="1.0" encoding="utf-8"?>

which is the "more" correct?

The XML spec says that processors "SHOULD" be match encoding names
case-insensitively. "SHOULD" is a technical term, less strong than
"MUST", but I can't see any reason why a processor would not do it.
