The point is that you did remove the common

      clock-names:
        description: List of necessary clock names.

from the top level, and added two copies of it under if/then/else.

Please keep common stuff as high up in the hierarchy as possible,
to avoid the need for duplication.
In this case, that means:
  - Keep the description at the top level,
  - Put only {min,max}Items and items under if/then/else.

I hope my explanation helps.

Gr{oetje,eeting}s,
