After talking with the testing group, the following properties should be REMOVED from the HTML5 device motion event documentation
We only support the following on HTML5 Device Motion:
We should also update the text at the top of the Device Motion Event page to not indicate that the hardware doesn't have a Gyroscope, but simply that we only currently support data from the Accelerometer and not the Gyroscope.
We should also drop the RotationRate object entirely from the docs
TowleT did some of these changes in pull #142, I'll cross reference this issue there as well
