		<xsd:documentation>2003-01-01: vocabualry terms were sea level and surface level
							2003-02-06: vocabulary terms changed because sea level was moved  the vertical datum level (vertGeodetic)
							2003-02-06: added datum level as a term because certain datums have a specified vertical base level
							2003-02-06  removed sea level as a term because it was added to the geodeticGlobalOrVert vocab; so no longer needed here;
							2003-02-06: removed surface level and replaced it with groud level to make it more clear
							2005-05-03: added Sea level because some geodetic systems (when not global?) have datum or vertical base levels specified separately (an that are different from) when a geodetic datum is specified.
