I know I'm being arsey here, but...

Is "radius" in XY space? What about Z? Does "accuracy" apply to X, Y, Z, M, all, some? Does "accuracy" have the same units for all ordinates? What if "accuracy" is different in value or units for different ordinates, or different at each vertex of a LineString, etc?

I fear that, unlike the geometry model - which is fairly robustly defined, apart from the higher dimensions, arguably - this is in danger of being under-specified and open to interpretation.

So I'm edging towards -1.
