/**
 * Specialization of {@link TilesView} for JSTL pages,
 * i.e. Tiles pages that  use the JSP Standard Tag Library.
 *
 * <p><b>NOTE:</b> This TilesJstlView class supports Tiles 1.x,
 * a.k.a. "Struts Tiles", which comes as part of Struts 1.x.
 * For Tiles 2.x support, check out
 * {@link org.springframework.web.servlet.view.tiles2.TilesView}.
 *
 * <p>Exposes JSTL-specific request attributes specifying locale
 * and resource bundle for JSTL's formatting and message tags,
 * using Spring's locale and message source.
 *
 * <p>This is a separate class mainly to avoid JSTL dependencies
 * in TilesView itself.
