RE: Decimal digit property - What's it for?

[Arcane Jill]

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 conclusions.

Understand that this is not MY definition. It came from Unicode public review issue #26 (http://www.unicode.org/review/pr-26.html). 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.
Jill
