Hi

How do I get SVGGraphics2D to prepend "svg:" to all of the SVG elements it 
creates?
Creating the factory document with the namespace doesn't do it and I can't 
seem to find any clues in the documentation or on the web.

Thanks
Murray

P.S. Here is my code: (I'm using swing tables as a cheat in producing 
tables in SVG)
