[Zope] Difference between "id" and id ?

[flight@mathi.uni-heidelberg.de]

Is it okay that

  <dtml-var id> and <dtml-var "id">

have different results ? I'm trying the following code in a DTML method inside
a ZClass, but the dtml-if fails since <dtml-var "id"> is empty.
<dtml-var id> OTOH shows the expected result, the id of the Seite object:

<table>
  <dtml-let selfid=id>
    <dtml-in "PARENTS[1].objectValues('Seite')">
      <tr><td><dtml-if "id==selfid"><dtml-var "PARENTS[-2].Images.littlearrow"></dtml-if></td><td><a href="../<dtml-var id>"><dtml-var font2><dtml-var title_or_id></font></a></td></tr>
    </dtml-in>
  </dtml-let>
</table>

This is with the most recent CVS Zope, FWIW.


I'd like to use this method to render a navigation sidebar that lists
the "sister" Seite objects of this ZClass object.
