ISO 3166/MA does have a concept of "merging" code elements. When a code
element is withdrawn, it is added to ISO 3166-3, and if its territory
(or nationhood or something) is absorbed by another country, the code
element of the absorbing country is made part of the ISO 3166-3 code
element. A classic case was the withdrawal of DD; since this was
effectively a merger of DD into DE, the ISO 3166-3 code element is DDDE.
This implies a statement on the MA's part about the relationship between
DD and DE.
An ISO 3166-3 code element is also created to reflect name changes (e.g.
Timor-Leste) or "splits" where the original country's code element is
withdrawn (e.g. the Soviet Union split into 15 countries, none of which
inherited SU).
When a code element is added, and none is deleted, there is no
comparable mechanism to express whether a "split" has occurred, although
it seems reasonable to assume that such a situation implies a split
(since virtually every inhabited area on Earth falls under an ISO 3166-1
code element). But the MA does not normally indicate that this is a
split, or what country is losing part of its territory. For example, in
