Seems like toNumber(geopoint) is working correctly (returning the accuracy value). Even if the Geopoint is not valid, it returns 9999999.0. I'm also a bit confused on the suggestion that GeoPointData should not implement IExprDataType but should be implemented by the data returned by GeoPointData. I don't see how that could be since the data returned by GeoPointData are built in types. It seems that the combination of the logic in XPathFuncExpr.toXXXXX and the GeoPointData.toXXXXX are effective.
