michael@0:    File Name:          15.9.5.6.js
michael@0:    ECMA Section: 15.9.5.6 Date.prototype.toLocaleDateString()
michael@0:    Description:
michael@0:    This function returns a string value. The contents of the string are
michael@0:    implementation dependent, but are intended to represent the "date"
michael@0:    portion of the Date in the current time zone in a convenient,
michael@0:    human-readable form.   We can't test the content of the string, 
michael@0:    but can verify that the string is parsable by Date.parse
michael@0: 
michael@0:    The toLocaleDateString function is not generic; it generates a runtime error
michael@0:    if its 'this' value is not a Date object. Therefore it cannot be transferred
michael@0:    to other kinds of objects for use as a method.
michael@0: 
michael@0:    Note: This test isn't supposed to work with a non-English locale per spec.
