I'm not sure I'm entirely understanding the problem you are trying to
solve, but I just tested the code below and perhaps it will at least
point you in a useful direction.  My test setup is a folder named
'testfolder' within which is a dtml document named 'testdoc'.  The
parent folder has a dtml method named 'test' containing the code
below, and a property named 'testprop' containing the string
'testfolder.testdoc'.  I think this code should work no mater where
the dtml-method and the property are located, ie: they should work
if defined on a class, but I haven't tested that.

Here's the code:

<dtml-call "REQUEST.set('o',PARENTS[-1])">
<dtml-in "_.string.split(testprop,'.')">
  <dtml-call "REQUEST.set('o',o[_['sequence-item']])">
</dtml-in>
<dtml-var o>

When I call this method, I see the rendered contents of my 'testdoc'.
Note that this code assumes testprop contains a complete path
sequence from the root folder (PARENTS[-1]).
