We should extend the syntax of keyframe selector to:
<keyframe-selector> = from | to | <percentage [0,100]> | <timeline-range-name> <percentage>

This includes a new syntax, <timeline-range-name>, which is defined only for view timeline now. For other cases, we ignore this keyframe selector:

Keyframes are attached to the specified point in the timeline. If the timeline does not have a corresponding named timeline range, then any keyframes attached to points on that named timeline range are ignored.
