I must say that I have a few reservations about the general
technique of adding new elements to SVG. I don't really know what
your constraints are but you might consider using a transformation
language like XSLT to map your custom grammer into standard SVG.
However if you really need to be able to use Java2D to do
rendering of the element this approach is probably the only feasable
one.

I suspect that you are not registering them with the DOM
implementation or the BridgeContext. If not you probably want to look
at batik.extensions.svg.BatikDomExtension, and
batik.extensions.svg.BatikBridgeExtension. Note that on top of
writing these classes you need to create a 'services' file, take a
look at the contents of 'xml-batik/resources/META-INF/services/', and
'http://java.sun.com/j2se/1.3/docs/guide/jar/jar.html#Service Provider'.
