I got the impression it is going to be that way.  A period of time
when it does not make a whole lot of sense, then one day...Eureka, it
all falls into place.

Perhaps in time.  I am paranoid of the idea of having the only copy
of my code existing in a database.  I prefer code being in text files
so it does not have to be rewritten from scratch if the database gets
corrupted.

Eventually it did work.  I had tried something like that before
posting to the list, but I had  which
returned the same results as .  Without the
quotes around title_src, I was getting a KeyError.  It turned out
that it was due to using "/Title.dtml" instead of "Title.dtml".  
Once I removed the '/', it worked.

Well, to be honest, I am not to crazy about the documentation.  It is
too obscure and too spread out.  IMHO, what is needed is a 'Zope
Quick Reference'.  Something like the PHP3 reference.  Then again,
maybe it's because I have yet to attain Zope Enlightenment. ;-)

Anyway, thanks for the help.  I'm sure I am going to have further
questions as I continue down this path.
