+      <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;attributeGroup ref="xml:specialAttrs"/>

+     <p>
