Sure. I think a lot of people would be happy about a tool like that. The way 
ZCML is constructed should make it very easy to retrieve all needed 
information, build RelaxNG schemas, etc.

Have you looked at "http://localhost:8080/++apidoc++"? It contains a 
dynamically generated ZCML documentation section. If you think that this 
facility is not well-organized you could easily contribute improvements 
there.

Note: This is a five directive, not a native Zope 3 one.

Books are for that. Both Philipp and my book explain what directives you need 
in the situations presented.

It is not really more verbose than Python.

Can you elaborate? I do not understand what you mean.
