Following example 18.3.1 and 18.3.2 from phillkon's book, i'm trying to
define a MySite class in Zope 2.12, which look like this:
class IMySite(IPossibleSite, IContainer):

The question then is, is it possible or would it make sense to do
something like this ?. Do you know about a sample code that could be
Any comment or hint would be very appreciated.
