Approved!
But maybe we also ought to file a feature request that if you don't
give an animator an attribute to animate, it shouldn't try to animate
the attribute named 'null'?

Summary: animator bug due to implicit coercion

Details:
Empty animators caused a subtle bug in swf9 because of implicit
coercion in swf9:
In swf9, 'undefined' can only be used for the any-type ('*'), for
any other type 'undefined' is coerced to 'null'. This is a problem
if you intend to use strict typing, but then forget some casts. In
this case, the "attribute"-property was casted to String in some
methods, but in several methods it wasn't. And if you later use
string concatenation (here: "e_" + attribute), you may get
"e_null" (coerced) or "e_undefined" (not coerced).
