Nope - use the JDOM adapters to get a Document from a specific parser
implementation. Nobody is familiar with DOMImplementation anyway...

You don't need to implement this method - you aren't implementing DOM in
DOMOutputter, you are creating a DOM Document.

For now just throw it over as a String - if/when we add CDATA to JDOM,
we'll cover that then.

Nope. Already went down that road, and vetoed it heavily. Bad news
(trust us, JDOM alpha 1 was like that, and James Davidson convinced us
