/**
   File Name:          15.9.5.6.js
   ECMA Section: 15.9.5.6 Date.prototype.toLocaleDateString()
   Description:
   This function returns a string value. The contents of the string are
   implementation dependent, but are intended to represent the "date"
   portion of the Date in the current time zone in a convenient,
   human-readable form.   We can't test the content of the string, 
   but can verify that the string is parsable by Date.parse

   The toLocaleDateString function is not generic; it generates a runtime error
   if its 'this' value is not a Date object. Therefore it cannot be transferred
   to other kinds of objects for use as a method.

   Note: This test isn't supposed to work with a non-English locale per spec.
