&1 is invoked by the JSP page to evaluate the
&2:&3 custom tag during the execution of the page.
Tag handler methods are called by the JSP page implementation class at
various points during the evaluation of the tag.
The tag handler methods in turn call methods on the underlying
Transformation Bean object, &4, to execute the methods.</p>

<p>If you need to extend or modify the functionality of the
&2:&3 custom tag, you can subclass this tag handler class.</p>
