Note that, to remove this copyright notice, you need to create a
derivative work.  Copyright law grants exclusive control of this to the
copyright holder.

If Zope wants their editor to always place a copyright notice in editted
documents, and they don't want to grant us the right to alter that part
of the code, they're within their rights -- but, of course, that would
greatly limit the utility of the editor.
