 196       This schema defines attributes and an attribute group suitable
 197       for use by schemas wishing to allow <code>xml:base</code>,

 199       <code>xml:id</code> attributes on elements they define.
 200      </p>

 202       To enable this, such a schema must import this schema for
 203       the XML namespace, e.g. as follows:
 204      </p>
 205      <pre>
 206           &lt;schema . . .>
 207            . . .

 217      </pre>
 218      <p>
 219       Subsequently, qualified reference to any of the attributes or the
 220       group defined below will have the desired effect, e.g.
 221      </p>
 222      <pre>

 224            . . .

 226      </pre>
 227      <p>

 229       with any of those attributes.
