30 August 2007 -- Wayland, Mass. -- On 4 September 2007, the Open Geospatial Consortium, Inc. (OGC) will release a corrigendum to fix problems in the GML 2.1.2 schemas. The changes include changing the official schema location to and fixing the other minor changes to the schemas so they validate by conformant processors. The ReadMe lists additional changes.
