Some searching turned up this website for CDF5:

I'm guessing this is more or less the official specification? If so,
it would be nice to update the official netCDF docs with it, too.

If not, I would encourage updating the specifications doc. One of
the strengths of netCDF (especially netCDF3) is that it is clearly
specified and has multiple independent implementations :).
