		<documentation>This XML Schema Document encodes the parts of the MD_DataIdentification class of ISO 19115 (OGC Abstract Specification Topic 11) which are expected to be used for most datasets. This Schema also encodes the parts of this class that are expected to be useful for other metadata. Both may be used within the Contents section of OWS service metadata (Capabilities) documents.
