    The core message of the caution page is the distinction between
    "approved" and "published". In the context of Unicode, "approved" means
    that something is "approved for publication", but for the user of the
    standard, the only thing that matters is what is published. Only at that
    point does it become formally part of the standard.

    On the ISO side, the process is similar, but governed by a different set
    of procedures than for UTC/Unicode. The publication timelines are
    necessarily also different, after all, these are different organizations.

    Nevertheless, the committees work together to make sure that when one
    standard is published it is synchronized with the corresponding version
    or amendment of the other standard, no matter whether that has already
    been published or is still forthcoming (publication process not completed).

    In other words, it's not the publication date that's synchronized, but
    the contents of the *corresponding* versions. The Unicode Standard
    carefully documents which is the corresponding version or amendment of
    ISO/IEC 10646 with which it is synchronized.

    Hope this helps,
