Developers API (and documentation) for Smart shapes and Widgets

It would be great if Xara would have some APIs and docs to let third-party developers to extend and develop new Smart shapes and Widgets.
I think everyone will benefits from this (including Xara).

As far as I know they were going to make it available for others to develop. But as you know the Xara boys & girls can be very, well how can I put this, secretive about the code they produce. Maybe if mwnz reads this request you will get more info from him as I thought the smartshape was run from a .js script.

I know nothing more than what Phil stated--that the documentation would be made available.

It is javascript and I have made a couple based upon what is supplied, looking through them all to see what the effects are. But it was really just an experiment in lieu of documentation. Hopefully Phil reads this and attaches it or let us know how to go about getting it.
