behavior is a module of CSS3 as far as I can see: 
http://www.w3.org/TR/css3-roadmap/#becss

So it already belongs to CSS somehow.

Speaking about animations as behaviors...
Let's assume we have some set of "standard" behaviors, then:

Master style sheet of some UA will be able to use:

img:animation {  behaivor: animate-image;  } 

And user will be able to define:

img:animation {  behaivor: none;  } 

on his/her end.

But behaviors define logic of actions. 
Animation in its turn is presentation atribute rather than 
logic. So it is under CSS umbrella I beleive.
