We covered this really recently on the list, so go back to the archives 
if you're curious about background.  Short summary is since XML parsers 
are mandated to normalize incoming \r\n line endings to \n we know that 
your \r was specifically requested and thus we try to preserve it on 
output for you.  If you want line endings as \r\n, then use \n as a 
logical newline in your setText() call and set the XMLOutputter to use 
\r\n when it outputs line endings.
