public void handleXML(RendererContext context, org.w3c.dom.Document doc, java.lang.String ns) throws java.lang.Exception
Handle an external xml document inside a Foreign Object Area.
This may throw an exception if for some reason it cannot be handled. The caller is expected to deal with this exception.
The implementation may convert the XML document internally to another XML dialect (SVG, for example) and call renderXML() on the AbstractRenderer again (which can be retrieved through the RendererContext).
