Hi All, Please note that Example 13 in 5.9.2. Creating a new Animation object (http://w3c.github.io/web-animations/#creating-a-new-animation-object) still uses AnimationSequence.
Additionally wihtout groups and sequences does it makes sense to introduce intrinsic iteration duration which is always zero? I think use "zero" instead of "intrinsic iteration duration" will simplyfy the spec and help reader. Sergey G. Grekhov
