Three of the four major browsers have partial or complete implementations of
SVG Animation 1.1 (SMIL). It's a solution that allows declarative animation
of vector images today. In Opera and Firefox (not sure about Webkit),
SMIL-animated SVG images are supported as <img> and CSS images. In the
browsers that support HTML5 parsing, SVG Animation is supported in an HTML
context. Quite a lof of demos and other content are using it on the Web.

You say that you don't think the Web should have two declarative animation
frameworks. But for the animated image use-case (including the advertising
niche currently served by Flash movies), I think CSS is inappropriate, since
the animation there is content, not style.

Given all that, personally I think we should keep SVG Animation and build on
it. We could diverge from the larger SMIL framework and simplify the model a
bit if we identify specific opportunities to do that.
