From: Edward C. Zimmermann > I think we need to be a bit more careful using our language. > 2004-06-uu is not an unspecified day in June 2004 but a "not as yet > specified day in June 2004". We, I feel, must think of "u" as a > placeholder and nothing other than a placeholder. That is why "2004-06- > uu" has day precision. The use of "u" is to explicitly declare that "at > some point in the future the respective u characters shall be replaced > by digits"--- this point in the future might be in 5 min or might be in > the Messianic Era. > An event that began on an unspecified day (unspecified since the > readability was limited to month) should use as its start 2004-06, e.g. > 2004-06/2004-07-03 Ed - if your argument applies only to a date within an interval than I can go along with it. And rather than say "at some point in the future ..." I think it would be best to remove the example. You're not suggesting that in a standalone date, a placeholder "u" always means that it will be filled in later, are you? --Ray
