Start State and End State Work Items
These types include a single work item each. The Start State work item is the entry point for the token of every workflow. It does not have inputs. The End State work item is the exit point of every workflow. It accepts only one predecessor and has no outputs. Every workflow must have one Start State and one End State.
The arrival of a token at the End State work item marks the end of the workflow. That token will be the one sent to the workflow engine, and the result of that token will be the result of the workflow. Its parameters are the ones that will be written to the directory according to the parameter list for the containing workflow.
