That example is ok, we use it over 4 years in many production systems. > I have not time to explore ans investigate basic elementary construction, > it is not a subject of research for programmer.

In case of JSP, use tr:document as Scott suggests. I case of facelets, you can use tr:document too or new h:head/h:body tags.
