When it works, it should look like this: (C1) Context1: Your bean above (C2) Context2: Implements the class C1: preprocess/Describe - we need somebody to implement the parameter class C2: .../Instantiate/etc. - I implement it C1: Can now proceed to instantiation using C2 as the iDependOn If there is no C2, then it is an error.
