Create Xalan DOM Document

[PSchanely]

Greetings all,
  I'd like to construct a document in memory and transform it.  Since I am
building it from scratch, I'd rather use a Xalan DOM than a Xerces DOM, but
I am unclear on how to create a new Xalan DOM Document.  My first guess was
to look for a static getImplementation() method on XalanDOMImplementation,
but I don't see one.  I must be missing something here...

Many thanks,
Phil
