      <xsd:documentation>This XSD provides a reference to the IMS meta-data root element as imsmd:record</xsd:documentation>
      <xsd:documentation>If the IMS meta-data is to be used in the XML instance then the instance must define an IMS meta-data prefix with a namespace.  The meta-data targetNamespace should be used.  </xsd:documentation>
      <xsd:documentation>2001-03-20, Thor Anderson: Remove manifestref, change resourceref back to identifierref, change manifest back to contained by manifest. --Tom Wason: manifest may contain _none_ or more manifests.</xsd:documentation>
      <xsd:documentation>2001-04-13 Tom Wason: corrected attirbute name structure.  Was misnamed type.  </xsd:documentation>
      <xsd:documentation>2001-05-14 Schawn Thropp: Made all complexType extensible with the group.any</xsd:documentation>

      <xsd:documentation>Any attribute declarations that have value="somevalue" changed to default="somevalue",</xsd:documentation>
      <xsd:documentation>attr.structure.req (hierarchical).  Removed references to IMS MD Version 1.1.</xsd:documentation>
      <xsd:documentation>Modified attribute group "attr.resourcetype.req" to change use from optional</xsd:documentation>
      <xsd:documentation>to required to match the information model.  As a result the default value also needed to be removed</xsd:documentation>
