Useful task attributes: Optional tasks

Defining a task as optional makes the task unnecessary for the completion of the process-description.

Typically, tasks are non-optional, that is, mandatory. This means that their parent-plan can only complete if the task is completed or discarded. As long as the task is dormant or in progress, the parent-plan remains in progress. When a task is defined as optional, its parent-plan can complete even if the task is dormant.
