Plugins can provide new Drag'n'Drop implementations for implementation of components and interface of services/references. These implementation are provided through two extension point : DragAndDropImplementation and DragAndDropInterface. The SCA metamodel can be extended with new plugins : for exemple new concepts can be added by extending the AnyExtension class. These new plugin should be able to provide new drag'n'drop implementation, so a new extension point DragAndDropAnyExtension can be added to the designer. There is now one drop listener which is based on SelectionTransfer, it enavles the drag'n'frop from the following views : Navigator, Package Explorer, ... Another drop listener based on TextTransfer should be added in order to enable drag'n'drop from other types of view.
