Hi All -
I agree with John Caron's wording.
It should be the responsibility of the application using auxiliary
coordinates
to respond "predictably". In many cases this would mean ignoring data
where
coords are missing, but that's not "unpredictable." Trying to draw a
point at, or
calculate a distance to, a null location would be unpredictable behavior.
I don't think this puts too much burden on software developers, but I'm
curious
to know if others see it differently.
Thanks - Nan
