/**
 * <!-- begin-user-doc -->
 * A representation of the model object '<em><b>Activity</b></em>'.
 * <!-- end-user-doc -->
 *
 * <!-- begin-model-doc -->
 * An Activity is a Work Breakdown Element and Work Definition which supports the nesting and logical grouping of related Breakdown Elements forming breakdown structures.  Although Activity is a concrete meta-class, other classes which represent breakdown structures derive from it; such as Phase, Iteration, Delivery Process, or Capability Pattern.
 * Activity represents a grouping element for other Breakdown Elements such as Activities, Descriptors, Milestones, etc.  It is not per-se a 'high-level' grouping of only work as in other meta-models, but groups any kind of Breakdown Elements.  For example, one can define valid Activities that group only Work Products Descriptors without any matching Task Descriptors.  Activities also inherit all properties from Work Breakdown Element and indirectly from Process Element; i.e. Activity is ready to have a full content description attached to it.
