Sublcassing isn't a solution in my case because I want to write a plugin. Any other user extension or plugin would also sub-class the base class and so only one set of extensions would be available. Subclassing also leads me to having to sub-class the sub-classed interfaces and the adapters and the viewlets - basically everything using the interface. Directly extending the interface from an external piece of code works to a point. from getpaid.core.interfaces import IPayable from zope import schema IPayable.vat_method=schema.Choice(title=u'VAT Method', values=[u'A', u'B']) The view "fields" are initialised when the class is declared, not when the views are created, i.e. the following element is ignored by @@edit- payable. I have to apply the same logic to the classes, i.e. import edit-payable and re-initialise the fields. This patching approach would work. However, I hope there is something cleaner.
