Check Zope's docs on variables:
http://localhost:8080/Control_Panel/Products/OFSP/Help/dtml-var.stx

<dtml-sqlvar expr="aq_parent.title" type="string">
might be what you're looking for. I don't know as I've never worked with 
aq_parent but this is one of the reasons why I stopped trying to work 
with DTML as it becomes sickeningly incomprehensibe.
