Implemented by tools supporting the editing process.
Clients may ask an IEditingSupport whether it is currently displaying a shell that has focus, and whether it is the origin of a document event. Depending on the answers to these queries, clients may decide to react differently to incoming notifications about events. For example, a special editing mode, that usually deactivates when the main shell looses focus, may decide to not deactivate if the focus event was triggered by an IEditingSupport.
Clients may implement this interface.
