		<xs:documentation>Geographic MetaData (GMD) extensible markup language is a component of the XML Schema Implementation of Geographic Information Metadata documented in ISO/TS 19139:2007. GMD includes all the definitions of http://www.isotc211.org/2005/gmd namespace. The root document of this namespace is the file gmd.xsd. This citation.xsd schema implements the UML conceptual schema defined in A.3.2 of ISO 19115:2003. It contains the implementation of the following classes: CI_ResponsibleParty, CI_Citation, CI_Address, CI_OnlineResource, CI_Contact, CI_Telephone, URL, CI_Date, CI_Series, CI_RoleCode, CI_PresentationFormCode, CI_OnLineFunctionCode, CI_DateTypeCode.</xs:documentation>
