Here, the 'xlink:role' attribute is used to indicate an assumed
well-known procedure for dereferencing netCDF Grid axes to a GML
domainSet. This - as well as having WCS provide netCDF as an output
format - is only possible if 'netCDF' has explicit well-defined
semantics that allow it to be interpreted. But it doesn't! Hence our
recommendation on CF-compliant netCDF as an additional WCS format.
I agree and would add that we need 1) to create a document explicitly
specifying the mapping of CF/Netcdf to WCS (if its trivial, it will be short!);
2) we need to extend CF in various ways needed for high resolution geolocation,
for example specifying Datum; and 3) we need to modify CF in a small number of
ways, eg allowing a valid CF file to not contain a lat/lon array.
I recommend we create a subgroup who are interested in this, and then actually do it!
