Geographic COmmon (GCO) extensible markup language
GCO is a component of the XML Schema Implementation of Geographic
Information Metadata documented in ISO/TS 19139:2007.
GCO includes all the definitions of http://www.isotc211.org/2005/gco
namespace. The root document of this namespace is the file gco.xsd.
The most current schemas are available at:
http://standards.iso.org/ittf/PubliclyAvailableStandards/ISO_19139_Schemas/

2012-07-13 Nicolas Lesage on behalf of the ISO/TC 211 XML Maintenance Group
* Update of readme.txt file and schema annotations
* Use of absolute schema locations of imported namespaces
* Simplification of the schema location of included XML Schemas
* Adoption of W3C Implementation of XLink:
- schemaLocation changed to: http://www.w3.org/1999/xlink.xsd
- xlink:simpleLink renamed xlink:simpleAttrs
* Addition of the version attribute to the schema element. The value of
this attribute is expected to be the date of the last release of the
XML schemas (e.g. 2012-07-13 for this release)
* Include root XML Schema document in all schema documents
Validation: Schemas have been validated with XML Spy 2010 Rel. 2 (MSXML 6.0)

* Change of GML namespace: http://www.opengis.net/gml (GML 3.2) =>
http://www.opengis.net/gml/3.2 (GML 3.2.1=ISO 19136)
Note: ISO/TS 19139:2007 (published 2007-04-17) normatively reference
ISO 19136 which was published 2007-08-23. The major change applied to
ISO 19136 is the change of the namespace URI. Previous release of GCO
are not compliant with ISO/TS 19139:2007
Validation: Schemas have been validated with XSV 2.10, Xerces J 2.7.1 and
XML Spy 2009 (2009-03-02, IGN / France - Nicolas Lesage / Marcellin Prudham)

* First official release of GCO
* GCO XML Schema files were generated from ISO/TC 211 UML class diagrams
in accordance with ISO/TS 19139:2007. The XML Schema generator is a
