@graybeal @martinjuckes @JimBiardCics - Thanks for your input. @martinjuckes : I agree the first sentence in the [Data Type section](http://cfconventions.org/cf-conventions/cf-conventions.html#_data_types) could be stronger. I would suggest simplifying your alternate sentence by dropping "assigned" and being more specific that these are all netCDF external data types supported by netCDF-4:
> "Data variables must be one of the following data types: ... _list of data > types_ ... (which are all the [netCDF external data > types](https://www.unidata.ucar.edu/software/netcdf/docs/data_type.html#external_types) > supported by netCDF-4)." -- You are receiving this because you are subscribed to this thread.
