* Usage example for HTML_QuickForm2 package: custom element and renderer plugin
*
* The example demonstrates a custom element with special rendering needs and
* shows how it can be output via a renderer plugin. The example element is
* a (much) simpler version of HTML_QuickForm_advmultiselect.
*
* It also demonstrates how to plug in element's javascript and how to use
* client-side validation with custom element.
