Please note where the above-cited reference says

    The precise format and semantics of additional strings is
    implementation dependent.

The paragraphs following that get even vaguer.  In particular, while
the standard clearly envisions that non-numeric zone ids should be
equivalent to some numeric zone id, the mapping between them is not
specified.  Hence it's impossible to determine validity, let alone
test equality, except by reference to some specific implementation's
behavior.

I really think this is something we shouldn't touch, at least not
till standard practices emerge.
