Ok, thanks for the feedback on that, Markus. But I'll reiterate what I said to Saašha: I would like to have specific use cases before adding this sort of complexity. For example,
"year unknown but month and date known"
"year and day of month known, but month unknown"
Which of these are useful (and why) and which are not?
