/**
 * <!-- begin-user-doc -->
 * A representation of the model object '<em><b>Task Descriptor</b></em>'.
 * <!-- end-user-doc -->
 *
 * <!-- begin-model-doc -->
 * A special Descriptor that represents a proxy for a Task in the context of one specific Activity.  Every breakdown structure can define different relationships of Task Descriptors to Work Product Descriptors and Role Descriptors. Therefore one Task can be represented by many Task Descriptors each within the context of an Activity with its own set of relationships.
 * A key difference between Method Content and Process is that a Content Element such as Task describes all aspects of doing work defined around this Task.  This description is managed in steps, which are modeled as Sections of the Tasks' Content Descriptions.  When applying a Task in a Process' Activity with a Task Descriptor a Process Engineer needs to indicate that at that particular point in time in the Process definition for which the Task Descriptor has been created, only a subset of steps shall be performed.  He defines this selection using the selectedSteps association.  If he wants to add steps to a Task Descriptor, he can describe these either pragmatically in the refinedDescription attribute or 'properly' create a contributing Task to the Task the Task Descriptor refers to.
