22  /*** IEntitySelection defines the interface to an entity collection class that  
23   * can store zero or more IEntity objects. The entities stored by this interface
24   * are type specified and must be defined by a single IEntityDescriptor. 
25   * The IEntitySelection differs from IEntityCollection by using a contained
26   * Qualifier to define the scope of the contained entity objects.
27   *
28   * IEntitySelection is ordered and contained entities can be accesed by index.
29   * Implementations to this interface must not accept duplicate entities.
