IAccessibleHostingElementProviders interface (uiautomationcore.h)
A Microsoft Active Accessibility object implements this interface when the object is the root of an accessibility tree that includes windowless Microsoft ActiveX controls that implement Microsoft UI Automation. Because Microsoft Active Accessibility and UI Automation use different interfaces, this interface enables a client to discover the list of hosted windowless ActiveX controls that support UI Automation in case the client needs to treat them differently.
