WFMF11 — WfRequeste and WfActivity inheritance - The Phanton Menace

Thanks for your consideration in discussing with me an importante topic. I think that you are one of the few persons that are fighting to put this facility in the reality plan. And I would like to still discuss these topics with you in the future.
I think that the goal of the WMF DTF is to define a standard that could be possible the componentization and interoperability of a workflow management system. We also know that only the definition of the interfaces (syntactic interoperability) is not enough to the componentization. It is also needed to define the semantic of this interfaces at formal level (and sometimes is also needed to specify non-functional requirements as part of the contract but this is a future problem). The last is very dificult to be achieved but is needed to create an open standard.
But as a scientist I will to disagree with some points about your arguments in order to justify the stripping of the inheritance relationship between a WfActivity and a WfRequester. I think that you like to be a kind of Object-Oriented Jake Stripper
