Thanks for your help, Pavlos. I found another way. Instead of writing:

<!--#var expr="_['sub-document'].author"-->

I wrote this, and it worked fine:

<!--#var expr="_.getitem('sub-document').author"-->

I found a way, but I don't understand why the first syntax worked fine with
Folders and fails with DTML Documents. If anyone would like to clarify the
semantic difference between _['sub-document'] and
_.getitem('sub-document'), I would be even happier.

By the way, Pavlo's site http://www.gaaros.com:9673/ is useful!
