I support this.  Is there justification for also including geo:alt?  In 
the same way that many records are now being generated by GPS assuming 
wgs84 and are hence labeled using geo:lat and geo:long, those same 
records often simultaneously have the altitude generated from GPS 
measurements.  Requiring the user to provide two values 
(dwc:minimumElevationInMeters and dwc:maximumElevationInMeters) is in 
this case redundant; the geo:alt value is just repeated for the two 
existing dwc:elements.
