Hello,
I am trying to construct an object tree. Every node in the tree is of
the same type. I am trying to achieve something like:
class INode(Interface):
parent = Object(
                title=u"Parent node",
                schema=INode
                )
children = List(
                title=u'Child nodes',
                value_type=Object(schema=INode)
                )
The above fails with "NameError: name 'INode' is not defined". Any clues
as to how to solve this?
This would be my first guess:

    class INode(Interface):
        pass
     
    INode.parent = Object(
            title=u"Parent node",
            schema=INode
            )

    INode.children = List(
            title=u'Child nodes',
            value_type=Object(schema=INode)
            )
