[Tobi, sorry for the delayed response.]

I agree with Tobi's sentiments. Most of the things he is requesting 
represent no fundamental architectural additions. They are just bells and 
whistles on the existing model. These things should be looked at for SVG2, 
as it is too late for SVG1.

Note that some of the features Tobi is requesting are already available in 
the SVG DOM, which already has some animation-related method calls on the 
SVGSVGElement, such as pauseAnimations().
