Exactly, a sample case is when your position is determined by your
network IP address. Geoclue can provide you with Country/Region/City.
It will also provide a lon/lat position for that city. Geoclue provides
an accuracy level to inform the consumer that this position is precise
to a city scale.
Such a field could be an improvement to the XEP. Geoclue provides the
where horizontal and vertical error is available on _DETAILED.
