Implementation of Operational Process incorrect

[bhaeberleinaa]

[devdoc/Operational Domain/Operational Process Viewpoint.md](../blob/main/src/devdoc/Operational Domain/Operational Process Viewpoint.md)
The realization here states that the pins of the Operational Process should be connected via an ObjectFlow to state the course of action in an Operational Process.
This is not possible that way in current SysML (or better in underlying UML). Operational Processes are realized with Activities. However, Activities cannot have Pins nor can they directly be connected using object or control flows. It should be the Operational Process Usages (aka the Actions) that have the Pins and that are connected.
