[css3-animations] animation-play-state value and multiple animations

The animation-play-state property [1] supports multiple values. The intent is most likely to reflect the state of each animation applied to the element - e.g. WebKit returns a computed value of 'running, running' when two are active- but the multi-value behavior is not really described in the spec. It would be helpful to define what happens in those cases where the animation-play-state list doesn't match the list of animations.
