      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/2009/01/xml.xsd"/>
     </pre>
     <p>
      Subsequently, qualified reference to any of the attributes or the
      group defined below will have the desired effect, e.g.
     </p>
     <pre>
          &lt;type . . .>
           . . .
           &lt;attributeGroup ref="xml:specialAttrs"/>
     </pre>
     <p>
      will define a type which will schema-validate an instance element
      with any of those attributes.
