[Zope] Namespace problem with folders starting with numbers

[Ausum]

I need to retrieve a property nested at a document placed within folders whose
names start with numbers. Like this:

<dtml-var "folder1.2000.12345.dtmldoc.this_property">

This sintax is invalid because there are object names that are starting with
numbers, within the Python expression. 

Is there a workaround? (I've tried the usual ones, unsuccessfully).
