The EiClasses::Location attriobutes need further refinement and definition. There are clearly many missing attributes associated with the gridCoordinates and the geoLocation. The gridCoordinates should be extracted from the UCA/IRC and/or CIM model and the geoLocation probably requires more discussion. For the GeoLocation we can either use something from the OGC (e.g. KML) or take a closer look at what they do in the CIM for geolocation. Personally I prefer KML.
