Yes, this is why we are trying to do. But people would have to specify
two filenames (one in SVG, the other in VML) to replace the pre-existing
symbol catalogue files and it's not still the ideal solution but perhaps
it's the only one.

Well, I hadn't considered using symbols in a georss feed and I don't
know well Georss format. For the moment, symbols are associated with
points geometry with a style.use="symbol" in the same way as images were
associated with style.externalGraphic. So, I haven't looked in detail to
the way you attach icons to GeoRss nodes but it seems that you would be
able to use SVG and VML symbols as well as images.

I hope to make progress before your development pause ends :-)
