// Recommendation E.164. It is a language/country-neutral representation of a phone number at a
// country level. For countries which have the concept of Area Code, the National (significant)
// Number contains the area code. It contains a maximum number of digits which equal to 15 - n,
// where n is the number of digits of the country code. Take note that National (significant) Number
// does not contain National(trunk) prefix. Obviously, as a uint64, it will never contain any
// formatting (hypens, spaces, parentheses), nor any alphanumeric spellings.

// Extension is not standardized in ITU recommendations, except for being defined as a series of
// numbers with a maximum length of 40 digits. It is defined as a string here to accommodate for the

// as there is no standard defined). However, only ASCII digits should be stored here.

// In some countries, the national (significant) number starts with one or more "0"s without this
// being a national prefix or trunk code of some kind. For example, the leading zero in the national
// (significant) number of an Italian phone number indicates the number is a fixed-line number.
// There have been plans to migrate fixed-line numbers to start with the digit two since December
// 2000, but it has not happened yet. See http://en.wikipedia.org/wiki/%2B39 for more details.
//
// These fields can be safely ignored (there is no need to set them) for most countries. Some
// limited number of countries behave like Italy - for these cases, if the leading zero(s) of a
// number would be retained even when dialling internationally, set this flag to true, and also
// set the number of leading zeros.
