<div>I would maybe call the third case a 'subBean".</div>

<div>I have also run into a problem regarding decorators of 'subBeans'.</div>
<div>The problem is that if I create a decorator of a subBean then I currently have no way of calling methods in the 'superBean'.</div>
<div> </div>
<div>I imagine that the spec may have to be extended with a DI annotation like @SuperBean (@SuperBean like the @Decorates annotation only it is set to a reference that delegates calls to the superBean instead of the the next method in the current stack of interceptors for the subBean).</div>
<div>@SuperBean would be used somelike this this...</div>

<div>baseTypeBean.create().getDescription().equals("BaseType");</div>

Minor clarification: in case 3, it does not make sense to inherit
binding types - rather, the user should be forced to *explicitly*
redeclare the binding types.
In case 2, binding types are inherited.
