In Latin American countries, every partner needs
to be identified even if he does not have the usual
VAT number (whatever it is called) e.g. you can also
be identified by your identity card.
We chose to put those types also in the vat field,
but to be clear what it is, we added a selection field
before the vat field which is VAT by default, but
is e.g. RUT (VAT of Argentina) when you choose Argentina
as country.
