Finally, I'll note that I've used the term "high-level configuration" to

Ok. The high-level configuration I'm thinking about is somewhere in
between. I don't know what to call it, so I won't call it anything.
Here's what has happened to me several times: I'm a Python developer,
writing simple code for Zope 3, and I follow Stephan's examples on how
to develop content types for Zope 3. I write simple schema-based
classes and simple directives. I've been conditioned to not repeat
myself in code; in fact, breaking that rule gives me a sick feeling.
So I proceed to follow Stephan's examples, which involves writing
similar ZCML directives for multiple classes. The repetitious classes
don't bother me because I know how to refactor them. But the ZCML
I've written gives me a sick feeling, because I don't know how to
refactor ZCML. The sick feeling doesn't go away, so I get scared of
Zope 3. Then I come here, hoping to find comfort.
Could you give a more specific example?
My attempt to solve the PyWebOff challenge, which I posted here:
http://mail.zope.org/pipermail/zope3-users/2006-March/002608.html
The ZCML I wrote in that message is quite representative of the ZCML I
wrote for a Zope 3-based system that's now in production. (The system
is a management interface for a Beowulf-style microfilm scanning
cluster.) The repetition isn't a showstopper, obviously, but it makes
me feel bad, so Zope 3 ends up being no fun.
