Re: [CF-metadata] [cf-convention/cf-conventions] Allow CRS WKT to represent the CRS without requiring comparison with grid mapping parameters (#222)

_If the CRS cannot be represented using the grid mapping parameters, using only the crs_wkt attribute is considered valid._ Sorry, but to my untrained eyes this essentially means software that purports to be CF compliant will have to be able to deal with WKT. It is very simple, I have a

Just to be clear, this proposal does not propose to remove or override the `grid_mapping` parameters. It's main goal is co-existence with the CRS WKT. Proposed WKT string statement modifications (modifications in italics): > The crs_wkt attribute is intended to act as a supplement to other >

I would suggest maybe going a little slow on this one, because my guess is many people are not following this discussion, so they will not be able to respond. I have no idea what for example Panoply does, the Coastwatch tools, Thredds, Seadas, and some others I can think of, and we
