I'll try to be more clear. 

I have a number of folders: "PrelimDocs", "HowToDocs", "HARPDocs", etc.

In each of these folders I have a number of objects: dtml documents,
files (pdf, MSWord, .zip and .sit), and some folders. 

The dtml method I posted is used in the index_html files of the the document
folders, to generate a index listing of the documents/objects in the
folders. 

My problem is that within some folders, there are documents (objects)
that I don't want to show up in the index_html dynamic listing. For that,I
had this idea I'd use this index_hide property. If I didn't want a document
to be listed, I'd just set an index_hide property for it. 

Better explanation?

Well, err, actually, for reasons I'm not entirely sure I could explain,
those methods don't work in this case. I worked with a number of the
fine gentlemen on #zope about the problem, and we discovered together
that nothing short of the full _['id'] would work.
