• coord: This is a list of values representing the coordinates.
• extraHeight: This is a separate value for the altitude/height. It is used: 1) if altitudes are stored in an own reference system (i. e. epsgCode refers to a GeodeticCRS rather than a CompoundCRS); 2) if there are no long/lat coords given or known but a height. See <geoCoord> for further notes.
• epsgCode: This is an URI pointing to the EPSG-Code (external link) as reference system for the coordinates in coord.
• heightEpsgCode: This is an URI pointing to the EPSG-Code (external link) for the separate altitude reference system.
