Identity Cards Bill

I am puzzled by Clause (1)(7)(b) as, in the context of the scheme of the Bill, it does not seem to make any sense. Clause (1)(3) says that,"““The statutory purposes are to . . . [provide] a convenient method for . . . individuals to prove registrable facts about themselves””." Dead men can prove nothing, and a dead man is not an individual, so how can the date of a person’s death be part of an individual’s identity?
