[Zope] Zope namespace question

Remote scripting?I'm confused by Zope namespaces. I'm trying to open a DTML document from a DTML method. The hierarchy is : Members/Staff/ADocument Info/Calendar/calendar.dtml That is, my DTML method is calendar.dtml and the document I wish to open is ADocument. How do I go about doing this? I want to get the contents of ADocument into a Python vector where it's split by it's newlines. I've tried : <dtml-let docContents=="_.string.split(ADocument.raw,'\n')"

but that obviously doesn't work because I don't have Members/Staff in the namespace stack. I've read the DTML doc in the Zope book but it didn't have examples like this -- that is, opening arbitrary locations in the hierarchy. Thanks.
