>          Components: extras

> Menu is not I18N-able. I have created a patch that fixes that. Here's an example of how to set a messagekey in menu.xml, that corresponds to an item in the messageresources.
> The message attribute tells the menu which key should be used to get the text from the message resources. (The $path variable can be used as well, since I adjusted the writeMenu VM macro to use: #evaluate($submenu) instead of $submenu itself. Velocity now supports #evaluate to evaluate a string that contains VM directives )
> <menu>
>     <menu label="Home" path="/home.htm">
>         <menu message="menu_logoff" path="$path?actionLink=logoff" roles="SU, DU, VU, WU"/>
>     </menu>
> </menu>
> The setParent method is overridden because the parent is needed to access the page's message resources. It will also recursively descend into the children as well. Once you add the menu to the page using Page.addControl(Menu.getRootMenu(new MyAccessController())); the page is set as parent for all menuitems.
> Attribute message takes precedence over attribute label. If both are set, message is the attribute used. 
> So there you go. I18N for Menu :)
