[CF-metadata] Need help writing point netCDF 3 dataset

Hi folks,

I'm writing a point netCDF 3 dataset which I've had no luck in getting 
either the IDV or netCDF (2.2) Tools to open (it does an NCDump but does 
nothing under the PointObs tab). It's essentially an XYZT dataset; I've 
included its CDL below. Can anyone tell me what I'm doing wrong, what 
I'm not doing that I need to do, and (or) send me an example point 
netCDF dataset that can be opened by the IDV and netCDF Tools?

Thanks *--* Mark

   ni = UNLIMITED;   // (99 currently)   // (has coord.var)
