 In the org.eclipse.papyrus.sirius.editor.representation.architecture plugin, a new class extending the AbstractCreateSiriusDiagramEditorCommand shall be created. This class will manage the condition of the creation of the diagram and the action to execute before creating it depending on the context.
 
-For example, a sequence diagram can be created directly under an interaction without prior action, but if we want to create it under a Model, an interaction shall be created before and defined as the root of the diagram.

 We created the Papyrus service '''org.eclipse.papyrus.sirius.editor.internal.sessions.SessionService''' initialized during Papyrus' launch. This service is in charge creating the Sirius Session and attaching it to the edited semantic resource (uml file). This way a Sirius Session will always be accesible even if the user didn't yet created a Sirius diagram.
