 * velocity-container is a special case: it should collect the information

 * the actual rendering of a component depends on the page and is not know
 * beforehand, we could include some css/js which turns out not to be needed
 * in this request, but it is cached by the browser anyway, so it should not
 * matter to much. a little advice if you want to do it perfectly : program
 * the controller in such a way that they make a component invisible if not
 * needed
