[cf-satellite] Coordinate variables - center vs. corner of the pixel

I'm wondering if there is a standard for center vs. corner when writing 
the coordinate variables for latitude/longitude or projection x/y of 
satellite imagery for netCDF?  GeoTIFF supports both conventions.  HDF 
appears to specify the UL corner of the pixel.  Has anyone settled on a 
convention for netCDF or CF Metadata in general?

Thanks,
