This interface is implemented by the Microsoft Active Accessibility to UI Automation Proxy to expose native MSAA properties and methods to UI Automation clients that need them for legacy reasons. The proxy automatically supplies this interface for applications or controls that implement Microsoft Active Accessibility natively. This interface is not intended to be implemented by UI Automation applications or controls.
