Well right now, there is nothing in the draft for a 'transition- 
triggered-animation' (or whatever we want to call it) that is part of  
the 'transition' shorthand. So nothing is defined for that, and we can  
make it work how we want.

Since it is not 'animation:', but rather an animation-value-like  
argument for a 'play()' function, we need to define how it works  
there. I've said how I think that should be defined.
