I thought about this approach and I think it is not going to work. The 
current model is that everything is in the DOM. Basically, there is no 
"hidden state" in SVG; the only such state is SMIL animation resolved time 
(things like foo.click resolved to actual clock time of the click). If we 
are to go with the model that allows one to change animated values 
arbitrarily, we'd have to agree that every element potentially holds hidden 
animated state. This is a fairly different model - and it has big 
implications for many useful optimizations.
