      Suppose we're running a special. First time zoo visitors get in
      for half price. Here's a DTML fragment that tests for a cookie
      using the *hasVisitedZoo* variable and displays the price
      according to whether a user is new or a repeat visitor::

        <dtml-if hasVisitedZoo>
          <p>Zoo admission <dtml-var adult_rate fmt="dollars-and-cents">.</p>
          <b>Zoo admission for first time visitors
               <dtml-var expr="adult_rate/2" fmt="dollars-and-cents"></p>
