XML Template Pages
     
         (XTP) {JSP} transformed by {XSL} stylesheets.
        An XTP page is basically a JSP page which specifies an XSL
        stylesheet.  The XSL specifies how selected tags in the XTP
        page should be rewritten.  All other tags are passed through
        unchanged and so treated as standard JSP.  JSP programmers can
        use XTP used as an easy introduction to XSL, incrementally
        applying styles to their pages.
