In xdfopen, xdef/ydef/zdef/tdef/edef each need the name of actual
dimension in the file as the first argument. No such dimension
actually exists for this edef (unless you build a super-file with
ncecat (NCO) or some such), so you will have to construct a
"full open" Data Descriptor File (DDF) of the "dtype netcdf" variety,
presumably. See:
