     44   This function retrieves the user readable name of a driver in the form of a
     45   Unicode string. If the driver specified by This has a user readable name in
     46   the language specified by Language, then a pointer to the driver name is
     47   returned in DriverName, and EFI_SUCCESS is returned. If the driver specified
     48   by This does not support the language specified by Language,
     49   then EFI_UNSUPPORTED is returned.

     60                                 to the driver writer. Language is specified
     61                                 in RFC 4646 or ISO 639-2 language code format.
