    No - this is not the AMD2 its the 'final proposed draft for AMD2', which
    is a document that is sent for ballot to WG2 member bodies. The FPDAM
    stage allows technical change - and there usually are technical changes
    as result of the ballot comments. Therefore this type of document is
    basically useless as information on what will be the precise contents of
    the published AMD2. Implementers are well advised not to rely on this
    document.

    The WG2 website is intended as a source of information for people
    helping develop 10646, not as a source of information for implementers.
    That's a crucial difference.

    You are referring to the summary of repertoire document. I usually
    prepare at least one per WG2 meeting, capturing the best available
    information at the end of the meeting for delegates to review. As part
    of their review, I may update fonts, or, more rarely, correct the
    spelling of names or code locations. My documents have no standing other
    than to help me make sure that my data files and fonts correctly reflect
    the committee decisions. They are intended for review, not as advance
    information for implementers.

    It is questionable whether you have the rights to duplicate material
    copyrighted by someone else without obtaining their permission, or for
    uses not covered by existing terms of use.

    The location http://www.unicode.org/Public/5.0.0/ contains files with
    file stamps as early as Oct 26 2005. Some files are in their 4th
    revision (...d4.txt). So, you can't have checked too carefully.

    Note that files in that location are the best available *preliminary*
    information about 5.0. The information is subject to change, based on
    review for correctness as well as further UTC decisions before final
    release. Unlike attempts (however well-meaning) to cobble together
    information from superseded ballot documents, these files are created by
    people who have access to the complete information on UTC and WG2
    technical decisions.

    Nevertheless errors are possible and users are properly cautioned -
    however, we encourage everyone to 'play' with these files and test them
    for consistency, correctness, etc. and report results using the Unicode
    Reporting Form.
