You can't add arbitrary attributes to JSF tags. So in order to make a tag role-sensitive in the way you've illustrated, you'd have to modify or subclass the tag to include the "role" attribute.
If you're using an off-the-shelf menu tagset, however, the more common way to handle that is to either dynamically modify the bindings to the menu tag or alternatively to use "rendered=" attributes to reference boolean properties in a backing bean.
Sometimes I maintain a "securityContext" JSF bean that can be interrogated when I need fine-grained security. So I'd do something like this:
