Simple Swing->SVG conversion: included links

hello batik devs/users,

freeplane (http://freeplane.org) uses batik to convert from swing to
svg:
  https://github.com/freeplane/freeplane/blob/1.5.x/freeplane_plugin_svg/src/main/java/org/freeplane/plugin/svg/ExportVectorGraphic.java
(and then uses that to convert to PDF).

Now, in order to have links in the PDF, I would like to add links to the
SVG. Is that possible at the above level (SVGGraphics2D), maybe
using callbacks?

Many Thanks and Happy Easter,
