The transformation half of the FragmentExtractor. This transformer sieves an incoming stream of xml with embedded SVG images and replaces the images with an xlink locator pointing to the image. Ultimately this could be much more general, but at the moment, I think it's mainly SVG extraction that's likely to go on, and afterall, you aren't gonna need it, so I've just used very simple extraction based on a URI and local name.
