Just for clarity, let me re-state the goal here:

Tags often contain partial dates or date times, e.g. just a year, or year and
month, or year month and day but no time. We want to be able to (a) signal this
correctly to applications, and (b) deserialise and re-serialise tags properly,
without loss of date/time information, but also without making up information
that's not there. "2012" is not the same as "2012-01-01" and when we read
DATE=2012 we want to later be able to write DATE=2012 again.
