Right now only statically defined Tag implementations are detected with the doclet that makes the Tag Reference for Jelly...
It would rock if we could instantiate each tag library and somehow introspect it to find its attributes for the reference.
e.g. the JellySwing tags typicaly map to a Swing component like JFrame, JTable and so on. Then each tag supports each property on the underlying bean.
if we could represent this in the Tag Reference it would make them much easier to use!
