+	 * Note that the real id attribute rendered in the browser may be
+	 * changed by the application container (for example, Portal containers may change
+	 * the rendered id value to ensure the uniqueness of
+	 * id's on the page). In this case, the real id rendered
+	 * in the browser may be looked up
+	 * through the JavaScript function <code>lookupIdByTagId( tagId, tag )</code>.
+	 *
+	 * <p>For example, assume that some tag's <code>tagId</code> attribute is set to <code>foo</code>.
+	 *
+	 * <pre>    &lt;netui:textBox <b>tagId="foo"</b> /></pre>
+	 *
+	 * <p>Then the following JavaScript function will return the real id attribute rendered in the browser:
+	 *
+	 * <pre>    lookupIdByTagId( "foo", this )</pre>
+	 *
+	 * <p>To get a &lt;netui:form> element and all of its children elements in JavaScript, use
+	 * the same JavaScript function <code>lookupIdByTagId( tagId, tag )</code>.  For example,
+	 * assume that there is a &lt;netui:form> whose
+	 * tagId attribute is set to <code>bar</code>.
+	 *
+	 * <pre>    &lt;netui:form <b>tagId="bar"</b> ></pre>
+	 *
+	 * <p>Then the following JavaScript function will return the &lt;netui:form> element
+	 * and its children (packaged as an array).
+	 *
+	 * <pre>    document[lookupIdByTagId( "bar", this )]</pre>
+	 *
+	 * <p>To retreive the value entered into a &lt;netui:textBox> within the &lt;netui:form> tag, use the following
+	 * JavaScript expression.
+	 *
+	 * <pre>    document[lookupIdByTagId("bar", this)][lookupIdByTagId("foo", this)].value</pre>
+	 *
+	 * <p>The second parameter ensures that the JavaScript function
+	 * begins its search within the correct Portlet scope.  Pass the
+	 * JavaScript keyword <code>this</code> as the second parameter.
