Ideally we shouldn't have such an attribute. Error checking and handling should be all done in the drivers, if possible. I don't remember exactly why it went into one of the original inertial sensor drivers. But I think it went there to provide error correction, in case plausibility/error checking of the delivered data failed. I also suspect it then got copied over and over again.
