\caption{Description of mandatory Skeletal Tracking CDF fields recorded for each frame. Any description ending with a $^\star$ is repeated once per player per frame. Any description ending with a $^\diamond$ is repeated once per player per frame per landmark (e.g knee\_left, hip\_right, ear\_right etc.). Note that \{i\} and \{j\} are used as indices for items in lists. Landmark names should follow snake-case with any direction indicator as a suffix. Any type ending with a $^\ddagger$ may be null when the subject is occluded, off-camera or otherwise not captured in that frame.}
