How to write a Xalan extension function returning DocumentFragment

[Arjen Haayman]

Hello,
I'm trying to write a Xalan extension function in Java that should return a 
DocumentFragment.
So far however I've been unable to figure out how to construct a 
DocumentFragment.

The only way I've found is Document.createDocumentFragment(), but how do I 
get a document?

This is the best shot so far:
[snip]
public Object toSVG( ExpressionContext context)
{
               Object retval;
               try
               {
                     Node node = context.getContextNode();
                     Document doc = node.getOwnerDocument();
                     DocumentFragment fragment = 
doc.createDocumentFragment();
                }
               catch( DOMException e)
               {
                       String error = Integer.toString( e.code);
                       Debug.Msg( 10, "error: " + error);
                       retval = error;
               }

               return( retval);
}
The result of this is that the createDocumentFragment throws a DOMException 
where e.code == 9.
I gather this means "Unimplemented".
