This schema definition ties together the various sub-components of the HapMap DCC XML Schema definitions (XSDs). This enables XML-document creators to reference only this file, or more likely a URL at which it resides, to validate their documents against the current HapMap XML schema. See each component .xsd file for further documentation and the files in the /xml-examples/"> directory The current revision of the HapMap schema can always be found at http://www.hapmap.org/xml-schema/ along with all schema releases leading up to it
