What happens when you put a "Start Workflow" action inside of an action set that has been marked to be run as workflow owner? Does the child workflow run as the permissions of the parent?
The Action Set action in Nintex Workflow is helpful not only from an organizational stand point but because it allows the workflow to run a set of actions as the workflow owner (the user who published the workflow, often the site admin).
Rather than giving a user contribute access to a list that they don't really need that access to or don't the workflow to fail and stop running because of a permissions issue, the actions can be placed inside the Action Set and the workflow owner will run the actions each time the workflow is ran.
