Some id attributes of Zope objects are methods, some are strings.

To account for every case:

  <dtml-in "objectValues('Foo Thing')">
    <dtml-let thing=sequence-item>
      <dtml-try>
        <dtml-var "thing.id()">
      <dtml-except TypeError>
        <dtml-var "thing.id">
      </dtml-try>
    </dtml-let>
  </dtml-in>

The need to do this will soon go away with the new "getId()" method mixed in
to all Zope objects.
