I want to try to break some of the recent discussion into smaller chunks. Can we focus in this thread on precision. To be honest, I don't really understand the issue, at least, not the requirement. Or perhaps, not the use case.
Anyway ...
I said
'{1960,1961,1962,1963} - this means in effect "all of the
(discrete) years, 1960 through 1963". It DOES NOT mean "the
(continuous) interval 1960 through 1963"'
And Ed replied:
But it is, in fact, the continuous interval 1960 through 1963 with precision of year.
A use case I have in mind is "year of publication". You want to record the years a book was published. Say it was published in each of the years 1960, 1961, 1962, and 1963.
Do you see this as a "continuous interval with precision of year"? I don't, because, for one thing, I'm not really certain what that means. Perhaps you could supply a better use case than "years of publication" to illustrate.
We can perhaps find a way to impose a precision indicator, but first I would like us to ascertain that it is both meaningful and required. And I would like to understand a use case or two to back it up.
