Subject: Another scoping issue - <>
Greetings! Continuing my slog through operators. ;-) Under <> we note that: "Note that in some user interfaces, this is displayed (or accepted) as “!=” or “≠”." OK, sure, that is a non-normative note. However, are we defining operators/functions and a standard syntax for the same or are we defining operators/functions in the abstract that may have a variety of representations? If the task is to create an interchange syntax for formulas used in OpenDocument spreadsheets, then the latter may be interesting but not terribly useful. For interchange purposes we should define one and only one acceptable syntax. (full stop) That others exist isn't something we can deny but we certainly aren't obligated to account for them. Maybe we don't share a common understanding of the purpose of standards. Standards, at least in my view, have as part of their reason for existence the elimination of other, possibly equally likely choices. That is how standards in information technology, for example, facilitate blind interchange of documents. Yes, a document may use any number of encodings but once it has said, UTF-8, all other possibilities fall to the wayside and both sender and receiver have a shared set of expectations. To the extent possible, I would like to see the same thing with OpenFormula. Hope everyone is having a great weekend!
