extension of validity

The fee charged at that time was $32 and postage for a three-year passport with the possibility of two years' extension of validity.

Also, the new passport does not accept modifications such as extensions of validity, and the updating of photographs due to ICAO's "write once" policy.

Empirical universality is, therefore, only an arbitrary extension of validity, from that which may be predicated of a proposition valid in most cases, to that which is asserted of a proposition which holds good in all; as, for example, in the affirmation, "All bodies are heavy."
