		<xs:documentation>Geographic Metadata XML (GMX) Schema is a component of the XML Schema Implementation of Geographic Information Metadata documented in ISO/TS 19139:2007. GMX includes all the definitions of http://www.isotc211.org/2005/gmx namespace. The root document of this namespace is the file gmx.xsd. This catalogues.xsd schema implements the UML conceptual schema defined in 7.4.4.1 of ISO/TS 19139:2007. It contains the implementation of CT_Catalogue, CT_CodelistCatalogue, CT_UomCatalogue and CT_CrsCatalogue.</xs:documentation>
