      9   ECMA Section: 15.9.5.6 Date.prototype.toLocaleDateString()
     10   Description:
     11   This function returns a string value. The contents of the string are
     12   implementation dependent, but are intended to represent the "date"
     13   portion of the Date in the current time zone in a convenient,
     14   human-readable form.   We can't test the content of the string, 
     15   but can verify that the string is parsable by Date.parse
     16 
     17   The toLocaleDateString function is not generic; it generates a runtime error
     18   if its 'this' value is not a Date object. Therefore it cannot be transferred
     19   to other kinds of objects for use as a method.
     20 
     21   Note: This test isn't supposed to work with a non-English locale per spec.
