pose angular velocity docs appear to state wrong frame

[TobiSchluter]

The driver documentation states

double vecAngularVelocity[ 3 ]; - The angular velocity of the device's tracking reference in driver world space, in radians per second. Used for prediction of the pose at the time when the application requests a pose for the device.

According to my experiments that is not correct. The angular velocity is given in a comoving frame.
