Forgot to say that in my example, I have "TestSubRendererHeader" as a
renderer type. So the registered renderer for this type should have
knowledge on how to appropriately render a header for this component
type. So in this case, the contract is the FacesBean having a "header"
property set or having a "top" faces present.

Or am I still off base in your concern?
