used to test for roles that are mapped to specific named Jakarta Servlets or
 named Jakarta Enterprise Beans. For a Servlet an example of this would be the <code>role-name</code> nested in a
 <code>security-role-ref</code> element nested in a <code>servlet</code> element in <code>web.xml</code>.

 <p>
 Should code in either such Jakarta Servlet or Jakarta Enterprise Bean wish to take such mapped (aka referenced, linked) 
 roles into account, the facilities for that specific container should be used instead.
