This is unnecessarily complicated. Simply do:

class DocTypeContainerVocabulary(ContainerVocabulary):
    containerName = 'doctype'
    zope.interface.classProvides(IVocabularyFactory)

Btw, the "classProvides" thing isn't "patching". Not sure what you mean,
Roger, but it looks like you wanted to give this a negative connotation.
