Description: This extension-point configures providers for the Global
ActionHandlerService ( org.eclipse.gmf.runtime.common.ui.serv-
ices.action.global.GlobalActionHandlerService ).
This service provides an extensible way to handle commonly used (global)
actions in different views and editors. These global actions might appear in a
view part context menu or might be predefined retargetable actions. The service
allows different handlers to be used, depending on the nature of the element(s)
selected in the workbench part. Each GlobalActionHandlerProvider regis-
ters itself for actions against a specific element type within a view part.
Configuration markup:
