[Zope] how do I show the contents of a sub folder using the dtml-in tag?

[Vion, Nicolas]

I have a folder called alpha containing a folder subalpha.
In a DTML document within alpha I want to list the contents of subalpha
using objectValues.

Basically I would like to use something like <dtml-in
"PARENTS[0].objectValues(['Folder'])">, but going DOWN instead of UP...

I haven't found anything in the various newsgroups (except for <dtml-in
"subalpha.objectValues(['Folder'])">, which does not work...).

Thanks in advance for any help.
