CSS Transitions and SMIL Animations are actually quite different. CSS
Transitions provide for smooth transitions whenever the computed value of a
CSS property changes; they provide no way to actually *cause* a change in a
property value. SMIL can cause changes in property values (changes that
occur during the cascade and therefore can be inherited etc), but it can't
automatically smooth transitions whenever a CSS computed value changes.
Because they're complementary, at Mozilla we're keen to support both CSS
Transitions and SMIL Animations (for SVG, at least). But discussion of CSS
Transitions vs SMIL Animation should happen on www-style, not in the
public-xhtml2 or whatwg lists.
"He was pierced for our transgressions, he was crushed for our iniquities;
the punishment that brought us peace was upon him, and by his wounds we are
healed. We all, like sheep, have gone astray, each of us has turned to his
own way; and the LORD has laid on him the iniquity of us all." [Isaiah
