The Zope Quick Reference.  An indispensible resource, which you can find 
through the zope.com Documentation section.

Another option is getChildNodes()

yuck....

<dtml-var member_name> is member of
<dtml-in "objectValues('team')">
  <dtml-in "objectValues('member')">
    <dtml-if "text_content() == member_name"><dtml-var name>, </dtml-if>
  </dtml-in>
</dtml-in>


that's my best guess, but you _might_ run into a problem with 'name'....

Have a better one,
