/**
* Set the ID of the tag.
* @param id the tagId. A value is required.
* @jsptagref.attributedescription <p>String value. Sets the <code>id</code> (or <code>name</code>) attribute of the rendered HTML tag.
* 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.
