Tag that renders the tag body if the current user known to the system, either from a successful login attempt
(not necessarily during the current session) or from 'RememberMe' services.
<p>
<p><b>Note:</b> This is <em>less</em> restrictive than the <code>AuthenticatedTag</code> since it only assumes
the user is who they say they are, either via a current session login <em>or</em> via Remember Me services, which
makes no guarantee the user is who they say they are.  The <code>AuthenticatedTag</code> however
guarantees that the current user has logged in <em>during their current session</em>, proving they really are
who they say they are.
<p>
<p>The logically opposite tag of this one is the {@link GuestTag}.
