Re: Formatting output

Whitespace outside the root element is inconsequential in the XML data 
model.  So this wouldn't matter except you're using a script that isn't 
really XML aware, and that's why it hasn't been added as a feature.

Two ideas that jump to mind:

* Subclass XMLOutputter

* Output the document in two parts and add a newline yourself in between 
the two parts
