28 * This class is intended to handle <class> element.
29 * This element specifies {@link Class} values.
30 * The result value is created from text of the body of this element.
31 * The body parsing is described in the class {@link StringElementHandler}.
32 * For example:<pre>
33 * &lt;class&gt;java.lang.Class&lt;/class&gt;</pre>
34 * is shortcut to<pre>
35 * &lt;method name="forName" class="java.lang.Class"&gt;
36 *     &lt;string&gt;java.lang.Class&lt;/string&gt;
37 * &lt;/method&gt;</pre>
38 * which is equivalent to {@code Class.forName("java.lang.Class")} in Java code.
39 * <p>The following attribute is supported:
40 * <dl>
41 * <dt>id
42 * <dd>the identifier of the variable that is intended to store the result
43 * </dl>
