To better illustrate what I have on my mind I'll show you some code from
Agora.

------- threads.php -----------
/* Set up the template tags. */
$template = &new Horde_Template();
$template->set('threads', $threads_list, true);

------ templates/threads.html ---------
 <loop:threads>
 <tr>
  <td class="<tag:threads.class /> nowrap">
   <tag:threads.link /><tag:threads.message_subject /></a>
   <span class="small">
    [<loop:threads.actions><divider:threads.actions>,
</divider:threads.actions><tag:threads.actions /></loop:threads.actions>]
   </span>
  </td>

You can note, that if threads.actions doesn't exist, you only see [, ] in
generated html code. And we cannot check it with
<if:threads.actions></if:threads.actions> because template engine only can
check top level array members for this, e.g. threads.

Hope that's understandable :)
