The NcML web page (http://www.unidata.ucar.edu/software/netcdf/ncml/) 
describes a number of ways to dump the NcML for a dataset: 1) Tools UI, 
2) using the netCDF-Java API, 3) netCDF-Java NcDump, and 4) netCDF C 
library ncdump, version 3.6.1 or later. I would guess that the 
Coordinates ON option is not supported by the last option. Also, not 
sure how to specify the Coordinates info in option 3.

Do you mean how should it be encoded in an enhanced catalog? Or what is 
the best way to get this information into an enhanced catalog?

Also, is it the variable information you want to include in an enhanced 
catalog or the coordinate information?

Thanks,

Ethan
