Why not use a datum:value pair? ele=[datum:]value
datum: is optional. If you don't know, just leave it out. Data users can assume locally signed or known. Thus, the spontaneous mapper and the elevation experts are served. Mapper communities can establish regional preferences. Quality checking can be applied. As usual with measures, unit may follow the value, where m is default.
