Puzzling indeed. Somewhere the test fails.. Could you do some debugger 
tracing or something? In DT_In.py, around the import lines, add 'import 
pdb', and in the renderwob method (renderwb without an 'o' is for #in tags 
in batch mode (i.e. using the size attribute), you should add the line 
'pdb.set_trace()' somewhere at the beginning, or at least before the test 
for string type. Now restart your Zope server.

When you now load the DTML Document, you'll notice that your browser will 
wait for the document. At the prompt where you started Zope, the Python 
Debugger prompt will be waiting for input. 's' is one step, 'n' is stepping 
over (do not go into a subroutine), 'r' is return from this method (it will 
first jump to the point where it is about to return) and 'c' is continue.

Now you can step to the test, and because you are in python, do some 
testing yourself. Let us know the results!

When you're done, you might have to hit 'c' several times, because of the 
fact that ZServer is multi-threaded. Remove the debugging code from 
DT_In.py, and restart your server. Again, it may be that you have to coax 
ZServer along with some more returns (repeats last command) or 'c's (when 
the last command has been blanked because you hit another 
'pdb.set_trace()'), before it actually will restart.

I would find it convenient as well, but I think DC had a reason to exclude 
string sequences. DC?
