    <div class="bodytext">
     <p>This schema defines attributes and an attribute group suitable
      for use by schemas wishing to allow <code>xml:base</code>,
       <code>xml:lang</code>, <code>xml:space</code> or
       <code>xml:id</code> attributes on elements they define.</p>
     <p>To enable this, such a schema must import this schema for the
      XML namespace, e.g. as follows:</p>
     <pre>
          &lt;schema . . .>
           . . .
           &lt;import namespace="http://www.w3.org/XML/1998/namespace"
                      schemaLocation="http://www.w3.org/2001/xml.xsd"/>
     </pre>
     <p>or</p>
     <pre>
           &lt;import namespace="http://www.w3.org/XML/1998/namespace"
                      schemaLocation="http://www.w3.org/2009/01/xml.xsd"/>
     </pre>
     <p>Subsequently, qualified reference to any of the attributes or
      the following group has the desired effect. For example:</p>
     <pre>
          &lt;type . . .>
           . . .
           &lt;attributeGroup ref="xml:specialAttrs"/>
     </pre>
     <p>This defines a type that schema-validates an instance element
      with any of those attributes.</p>
