 *
 * <!-- begin-model-doc -->
 * A Work Product Descriptor represents a Work Product in the context of one specific Activity.  Every breakdown structure can define different relationships of Work Product Descriptors to Task Descriptors and Role Descriptors.  Therefore one Work Product can be represented by many Work Product Descriptors each within the context of an Activity with its own set of relationships.
