This interface is not completely undocumented. It doesn’t get even a declaration in any Windows SDK header, but the corresponding IID_INavigationBand is defined in the UUID.LIB library.

HRESULT SetNavigationTarget (INavigationTarget *);
HRESULT SetNavigationState (ULONG);
HRESULT SetTrustState (ULONG);
HRESULT SetProgress (NAVIGATION_BAND_PROGRESS_STATE, LONG, LONG);
with the following type definition presumed for the undocumented enumeration:
typedef enum tagNAVIGATION_BAND_PROGRESS_STATE NAVIGATION_BAND_PROGRESS_STATE;
It is not entirely inevitable, but the INavigationTarget interface is also undocumented.
