/**
 * Creates an outputter and writes an XML tree.
 *
 * The encoding argument here only sets an attribute in the
 * XML declaration. It's up to the caller to ensure the writer
 * is encoding bytes to match. If encoding is null, the default
 * is "UTF-8".
 *
 * If XML character entity escaping is allowed, otherwise unmappable
 * characters may be written without errors. If disabled, an
 * UnmappableCharacterException will make their presence obvious and fatal.
 *
 * LineEndings will be CR-LF. Except for comments!?
 *
 * @param doc
