The alpha-3 code the country code resolved to.
The same masks in imask's pattern syntax (0 a digit, a a letter, * any
character), as imask's dynamic-mask list: IMask(input, { mask: imask }).
One mask per compact length the ID comes in. Tokens: # a digit, L a letter, X a letter
or a digit, * any character except whitespace; every other character is a separator.
Matches an ID written in any of the masks, in uppercase: the form formatId()
returns. Usable as react-hook-form's pattern rule.
A country's input masks, in this library's vocabulary and in forms libraries use.
