    In fact what I'll do is to replace that by a JavaScript version, whose source
    data will be feeded and cached (in the server) from the Unicode normative text
    file, to generate a Javascript array. The "colored" version was there to help
    show what I found.

    Michael said that he will ignore all differences found in the previous HTML
    files, considering only the text file as the source and adding the missing
    elements.

    Since then, there has been no clear justification for the removal of Georgian
    Asomtavruli (I was told that the two scripts were being disunified in Unicode,
    and it is already for bibliographic references, and considered distinct by most
    Georgian readers that can't read it, but can read perfectly the default
    Mkhedruli script variant with various combinations of diacritics for
    transliteration, that could not work correctly if written with the Asomtavruli
    variant).

    So the 4-letter code has been published for some time, but only with a
    conflicting 3-digits numeric code. As most users of ISO15924 will ignore the
    numeric code in most applications, they may already have started to tag their
    Asomtavruli references with "Geoa" (it was said that it was valid and
    standard...) instead of Private Use codes (in Qaaa to Qabx). Will they need to
    revert them? What if documents or books have already been printed in Georgia
    using the "Geoa" code in their references? Or if this has already been used to
    feed librarian indices for interchange?

    May be there was no prior approval of this code and the publication was delayed
    for later and should not have been published... Oh well...

    Thanks to Michael for the addition of PropertyValueAlias="Common" for
    Code="Zyyy", and the correction of the incorrect HTML syntax of NCRs. I would
    have much prefered the absence of line wrap in this code (copy/paste operations
    by developers will insert an undesirable additional character that may be
    unnoticed in sources).
    On the opposite, there was no real need to prohibit line wraps in the Date
    column.
