An object implementing '<<(String)', to which the output will be written.

indentation

An integer greater than 0. The indentation of each level will be this number of spaces. If this is < 1, the behavior of this object is undefined. Defaults to 2.

If true, the printer will insert whitespace before closing empty tags, thereby allowing Internet Explorer's feeble XML parser to function. Defaults to false.
