Dear Martin I would think that since words are blank-separated, they ought to be allowed to include any character except white space. The convention says "If multi-word phrases are used to describe the flag values, then the words within a phrase should be connected with underscores." To allow phrases including spaces, we'd need a different convention, such allowing flag meanings to be an array of strings i.e. a 2D character array. I don't think that's possible in netCDF- classic for an attribute, so the attribute would have to point to a variable instead. If it is possible in netCDF-4, we could make it a feature of CF specific to netCDF-4. Up to now we have not used new features of netCDF-4 in the CF convention. Either way, a change to the CF standard would be required.
