Hi Andre,

You need to add the ConstrainTypesMixinSchema to your schema. So on your 
content type in your imports put:

from Products.ATContentTypes.lib.constraintypes import 

and, add that schema to your declaration

schema = YourSchema + ConstrainTypesMixinSchema

That should work fine then. You shouldn't need to update your schema, just 
restart the server.
