In some cases a monument has been shattered, or is so damaged, or missing so many pieces that its re-erection over a grave in the exposed conditions of a graveyard is not considered practical. In such instances it is still

considered desirable that the monument be retained within the cemetery or burial site. Details of the original location of the monument fragments should be recorded.
