[netCDF #AES-723647]: Can't open HDF5 attribute

Hello,

The netCDF utilities are not guaranteed to be able to open hdf5 files, as not 
every feature implemented in libhdf5 is used/supported by the netCDF library.  
Similarly, h5dump is not guaranteed to be able to properly represent a netCDF4 
file; while it will be able to read it, netCDF offers features (such as shared 
dimensions) that are not supported natively by libhdf5.  The best bet will be 
to use the netCDF utilities to read netCDF files, and the hdf5 utilities to 
read generic hdf5 files.

I hope this helps!
