    <xsd:annotation>
        <xsd:documentation>This document defines an XML schema for XML instance documents, or fragments thereof,
that represent document reference information that is designed to populate the "Normative references" and "Bibliography"
clauses of documents that conform to the ISO guidelines for international standards.
This XML schema is a building block for import into larger XML schemas, such as machine readable profiles (see DSP8028).
This XML schema uses the "Venetian Blind" design pattern for the most part. In that pattern, only the XML elements
intended to be used as root elements are declared as global elements in the XML schema, and all relevant XML types are
declared as global types, for internal use by the XML schema. Any global types are not intended to be used by referencing
XML schemas.
This XML schema maintains forward compatibility with respect to its XML instance documents as follows:  An updated minor version
of the XML schema (for example, "m.n+1.*") shall successfully validate XML instance documents that validated successfully using
the original version of the XML schema (for example, "m.n.*").  An XML instance document that successfully validates against an
updated minor version of the XML schema may or may not validate against the original version of the XML schema.
In other words, the XML schema may introduce additional functionality as long as it does not break existing XML instance
documents.</xsd:documentation>
