[Zope-CMF] GenericSetup ATContentTypes global_allow

[Katja Süss]

Hi *
How can I do 
    for type in types: 
        if type in NOT_IMPLICITLY_ADDABLE:
            t = pttool.getTypeInfo(type)
            t.global_allow = 0
for standard ATContentTypes
when using GenericSetup for a product?
Thanks for any hints,
Katja
