    Thanks, Jim. You're the only respondant who has actually bothered to
    answer my specific question 'What possible use could any mechanical
    algorithm make of the "decimal digit" property that it could not equally
    well make of the "digit" or "numeric" properties?'. Nobody else even
    made the attempt. /However/ - since you don't agree with the original
    predicate (the definition of the Unicode "decimal digit" property), it's
    not surprising that logical reasoning should lead you to different

    Understand that this is not MY definition. It came from Unicode public
    review issue #26 ( From my
    (purely logical) point of view, a definition is not something you can
    agree with or disagree with. It is simply an axiom from which
    conclusions may be logically derived.

    So, EITHER this is axiomatically the correct definition of "decimal
    digit", as used by the Unicode consortium, OR it isn't. If it is, then
    my question stands, and remains unanswered. If it isn't, then it is my
    /original/ question (how does the Unicode consortium define the "decimal
    digit" propery) is the one which remains unanswered.

    Thanks again.
