23    File Name:          15.5.4.11-2.js
24    ECMA Section:       15.5.4.11 String.prototype.toLowerCase()
25    Description:
26
27    Returns a string equal in length to the length of the result of converting
28    this object to a string. The result is a string value, not a String object.
29
30    Every character of the result is equal to the corresponding character of the
31    string, unless that character has a Unicode 2.0 uppercase equivalent, in which
32    case the uppercase equivalent is used instead. (The canonical Unicode 2.0 case
33    mapping shall be used, which does not depend on implementation or locale.)
34
35    Note that the toLowerCase function is intentionally generic; it does not require
36    that its this value be a String object. Therefore it can be transferred to other
37    kinds of objects for use as a method.
