28  * Custom tag to generate hyperlink that can invoke instance of
29  * ListBrowserServlet and display a specific page. This class implements
30  * functionality similar to methods in listdata.js but only based on the data
31  * available at the time when the page is generated. If the page dynamically
32  * changes some of the list data pattern variables for example based on users'
33  * action, you should use methods in the listdata.js instead. Keep this
34  * functionality synchronized with the one provided by the JavaScript file.
