Takes care of uppercasing fields where required by the format (to faciliate
automated mail sorting).
Requires specifying the origin country code, allowing it
to differentiate between domestic and international mail.
In case of domestic mail, the country name is not displayed at all.
In case of international mail:
1. The postal code is prefixed with the destination's postal code prefix.
2. The country name is added to the formatted address, in both the
current locale and English. This matches the recommandation given by
the Universal Postal Union, to avoid difficulties in countries of transit.
