/**
 * This annotation is used to select request handlers based on
 * request parameters. For example, in a single resource URL, you
 * may wish to call different handlers for POST based on the request
 * parameter "action" (action=update, action=delete, etc.). These
 * maybe modeled as form parameters or as part of the query string.
