I don't think it's out of hand to add new graphical features, especially
when they are so simple to implement. I think most of the complaints were
about difficult features like filters, or about non-graphical things like
network protocols.

Yes, I discuss it on the page I referenced. sXBL *might* allow you to
preserve the semantics of a star/regular polygon, if it were a geometric
language that were being represented, but it makes no sense to me to add a
layer of geometry and script just to achieve an effect in what is a
geometric language, SVG... And those semantics (for screen readers, image
indexers, and other SemWeb thingies) would only be available if the
arbitrary language were well-defined and well-known as a standard.  

Second, a wide variety of SMIL animation effects that could be achieved with
this element (animating the number of points, the radii, etc.) would be nigh
impossible without a boatload of script to do the animations, which defeats
the purpose of having SMIL animation.

Doug
