I think that is the correct approach for the standard name, and if you have a need for it now, please propose such names. Of course, the above leaves the the reference surface unspecified. I would argue that if the reference surface has a geophysical meaning, it should be identified in the standard name e.g. water_surface_height_above_mean_high_water What sort of surface is NAVD88, if not an ellipsoid or a geoid? (Excuse my ignorance - I am not a geodesist).
