Template:ISO 3166 code/doc

This template allows parameters for country and top-level subdivision, returning the ISO 3166 code. It is a slightly more verbose and inefficient alternative to the writing:



but it allows for more graceful error handling.

Usage
Example:



Support for aliases:

Support for province aliases is built in to the collection of Category:ISO 3166 name from code templates for example:


 * ISO 3166 code Afghanistan Bāmīān
 * ISO 3166 code Afghanistan Bamian

The same is true for country aliases at the county level



The mechanism here is, however, redirection. This allows for more equivalent constructs such as
 * (The first mark is whether it is actually supported, the second whether all calls of that type should be expected to work.)
 * (The first mark is whether it is actually supported, the second whether all calls of that type should be expected to work.)
 * (The first mark is whether it is actually supported, the second whether all calls of that type should be expected to work.)

Here "United Kingdom" is the canonical country name, "UK" is an alias. The plan is to support all reasonable constructs of the forms 1-5, and any common (and not counter-productive) constructs of the form 6.
