I just saw Don Box and Chris Anderson give their talk on XAML, Longhorn and Indigo (oh my!). XAML seems very SVG like (from a markup perspective), especially the TransformDecorator's. The TransformDecorator is equivalent to a SVG filter.
Is there a predefined set of TransformDecorator's and can we create our own just like in SVG? I guess I'll have to wait until I can get my hands on that Virtual PC image and get knee deep in it. Until then I'll read Rory's Blog and laugh until snot runs out my nose.
