Defines the supported animation styles.
Keyframe animations are driven linearly from beginning to end. This animation style results in a repetitive playthrough of the animation, such as in a walking motion.
Keyframe animations should not be driven directly by the viewer application. This value is used by documents that are intended to drive animations through an alternate means, such as JavaScript.
Keyframe animations should oscillate along their time range. This animation style results in a back-and-forth playing of the animation, such as exploding or collapsing parts.
