Hi Chris,
One comment regarding the use case with VNF package hand-over to SDC for on-boarding. To my understanding there is no need to translate TOSCA to HEAT because the TOSCA/CSAR on-boarding is within a scope of SDC Amsterdam release.

Another question regarding VNF-SDK-UC-05-01-02 and VNF-SDK-UC-05-01-03: Do you expect receiving the requirements from the VNF Requirements project and how do you think to deploy/instantiate and run the VNF in order to test its life-cycle and functionality?

I would propose that we also use Papyrus to create use case diagrams.
