A context item represents a piece of transient state in a designer. Context items are managed by a ContextItemManager, which is part of the EditingContext employed by a WorkflowDesigner when representing the workflow model visually. The ContextItemManager is returned by the Items property which contains the data that is shared between a host and the designer. This data provides the mechanism needed to hook into subscription and change notification.
