-// This file contains an implementation of RFC 5893: Right-to-Left Scripts for
-// Internationalized Domain Names for Applications (IDNA)
-//
-// A label is an individual component of a domain name.  Labels are usually
-// shown separated by dots; for example, the domain name "www.example.com" is
-// composed of three labels: "www", "example", and "com".
-//
-// An RTL label is a label that contains at least one character of class R, AL,
-// or AN. An LTR label is any label that is not an RTL label.
-//
-// A "Bidi domain name" is a domain name that contains at least one RTL label.
-//
-//  The following guarantees can be made based on the above:
-//
-//  o  In a domain name consisting of only labels that satisfy the rule,
-//     the requirements of Section 3 are satisfied.  Note that even LTR
-//     labels and pure ASCII labels have to be tested.
-//
-//  o  In a domain name consisting of only LDH labels (as defined in the
-//     Definitions document [RFC5890]) and labels that satisfy the rule,
-//     the requirements of Section 3 are satisfied as long as a label
-//     that starts with an ASCII digit does not come after a
-//     right-to-left label.
-//
-//  No guarantee is given for other combinations.
-
-// ErrInvalid indicates a label is invalid according to the Bidi Rule.
