[VK] True, but Chimezie's question still remains valid. I wonder if someone has developed guidelines on when something is a version vs a new class? > > So, my example still stands.

[VK] The only difference is I do not view it as a version in the content management sense. IMHo, it's more appropriate to view and model as a dynamic state variable changing over time. ---Vipul .
