Hm, you're right, there might be some scenarios:
* simple example, the animated value changed by JS (IIRC the spec wants us to proceed the animation and set the baseVal afterwards, take a look at it)
* the animation is a children of the target and we change the hierarchy in the DOM. I would expect that the animation stops or, that the old parent still gets animated till the animation stoped.
* the IRI of the target changed, or more worst, another element gets the id of our current target. This is a bit more complicated and will not work with this patch. Not sure how we could handle it at all. Maybe we use the Resource handler to give back changes to the animation API. hmm..
