// Checks we have at least three leading digits, and only valid punctuation,
// alpha characters and digits in the phone number. Does not include extension
// data. The symbol 'x' is allowed here as valid punctuation since it is often
// used as a placeholder for carrier codes, for example in Brazilian phone
// numbers. We also allow multiple '+' characters at the start.

// they are entered as "15" etc, but only if there is no punctuation in them.
// The second expression restricts the number of digits to three or more, but
// then allows them to be in international form, and to have alpha-characters
// and punctuation. We split up the two reg-exes here and combine them when
// creating the reg-ex VALID_PHONE_NUMBER_PATTERN itself so we can prefix it
// with ^ and append $ to each branch.
