Dear David
It's a good idea to consider what would be a better name than `transform`
for this concept, but I have concerns about calling it `coordinate
reference system`. The main purpose of `grid_mapping` is to specify how 2D
lon and lat coordinates are related to 1D projected or rotated
coordinates. That doesn't sound like a function which I would call
"coordinate reference system", though it may involve a CRS. The
relationship between dimensional and dimensionless vertical coordinates,
which we also include in `transform`, does not usually involve a CRS.
Perhaps we should consider distinguishing the reference and transformation
aspects of `grid_mapping`. We could decide to regard them as two different
parts of the logical model, even though they are joined in one netCDF
mechanism.
Cheers
Jonathan
