I think you might be missing an else: and a couple or three tabs. ;)
If I'm not wrong this should have a pretty elegant DTML equivalent:
<dtml-in PARENTS>
<dtml-with aq_explicit only>
<dtml-if propname>
<dtml-return proname>
<dtml-else>
<dtml-raise AttributeError><dtml-var propname></dtml-raise>
</dtml-if>
</dtml-with>
</dtml-in>
I'm not going to actually *test* it. Whether it works is left as an
exercise to the reader.
