Class diagram for Number Sequence Framework [partial]

In continuation to a post written several months ago [http://dotnetxperience.blogspot.com/2012/07/number-sequence-framework-in-dynamics.html ], I thought to make a class diagram in order to show all the related objects required for successfully implementing the number sequence framework. The original motive was to write one COMPLETE post depicting all aspects fo the framework however i am not satisfied from my effort. I will improve it for all of you and for myself as well.

At the moment, I am sharing the class diagram. It s not the best of them, but for sure it will assists all of us in better understanding of the framework.
