Some questions about the interpretation of time-intervals:
1. Does 2004-01-01/2004-01-10 include January 10, or does it end at
2. Is 2004-01-01/P10D equivalent to 2004-01-01/2004-01-10 or to
3. Is 2004-01-15/P1M equivalent to 2004-01-15/P30D or to
4. Is 2004-03-31/P1M equivalent to 2004-03-31/P30D or to
