[Zope] Render DTML Document title inside another DTML Document in parent folder

Is there a way to reference a DTML Document's title in the folder 2-level deep from another DTML Document in the parent folder? The hierarchy looks like this: FolderA Doc1 FolderB FolderC Doc2 FolderA contains DTML Document Doc1 & FolderB. FolderB contains FolderC. FolderC contains DTML Document Doc2. Doc1 is called from Doc2 using <dtml-var Doc1> In Doc1, I want to display Doc2's title. I tried <dtml-var title>. But it rendered Doc1's title instead of Doc2's title. How can I render Doc2's title?
