Hi John,
Actually the way the data is organized, LON and LAT are not coordinate
axes but dependent variables, so wouldn't it be

You could say that the fact that they are "dependent variables" is
expressed by the dimensionality LAT(TAXIS), LON(TAXIS), rather than
LAT(LAT), LON(LON).
anyway, coordinates here means the georefrenceing coordinates and you
do need them in that attribute.
