[Zope] using DOM from within Zope

[Dennis Allison]

A common approach is to isolate the functionality that uses the module(s) 
and put them in an Exernal Method or write a Product that incorporates 
them.  These approaches give much more freedom than Python Scripts which 
are given limited access because of security issues.
