// Contains interface definition for IPassportService.  Any component

	HRESULT Shutdown();

	// Part 1 of a two-part call.  This call indicates to the component that it should
	// get ready to refresh any state that it holds.  The externally visible state should
	// remain the same to any outside objects using this component.  This call expects that
	// the component will cache the new state until Part 2.
	HRESULT ReloadState([in] IServiceProvider* p);

	// Part 2 of a two-part call.  The component should now swap the old state with the new
	// state it cached in the call to ReloadState().
	HRESULT CommitState([in] IServiceProvider* p);

	// This is for runtime diagnostics.  The component should SysAlloc:: a buffer containing
	// formatted information that describes the current internal state of itself.  Caller
	// is responsible for freeing the memory.
	HRESULT DumpState([out,retval] BSTR* pbstrState);
