This reminds me of something I was going to mention but forgot about.
How about allowing the .animVal properties of the various SVGAnimated*
types to be read-write?

The reason I'd like this is that sometimes you want to animate (or cause
other temporary modifications to) elements with script and not SMIL.
While there is a way to make reversible changes to any CSS properties by
modifying the override stylesheet, there's no parallel for attribute-only
properties.

The particular example I have in mind is (of course) my CSVG extensions.
I want to make a pure script implementation of this and it would be a
lot nicer if I could simulate the animation of attributes without
actually modifying the base value.  I could work around it by having an
'set' element as a child of the relevant element and just modifying its
'to' attribute.  This isn't as clean as the override stylesheet is for
CSS properties.

OR... will I be able to do this with the DOM trait stuff?

*has another poke around the 1.2 draft*

Just noticed the traitDef stuff.  That looks good.

Thanks,

Cameron
