+        <description>
+            Check to see that the user is logged in (optionally at a certain minimum level).
+            If not, then redirect them to the login page, with the current request stored as
+            a post-login destination.
+            
+            If "level" is specified, then the user must be logged in at least at that level
+            in order to avoid being redirected. "level" may be a String like "DBA" or "EDITOR",
+            or it may be an integer like 50 or 4.
+            
+            If "bean" is specified, it is taken as the name of a request attribute where the
+            LoginStatusBean will be stored.
