Note that current CSL doesn't give us a way
to distinguish between /open and /unknown,
so item3-3 and item3-4 get parsed similarly.
That should change in CSL 1.1, and then this
test should be revised.

@article{item3-3, date={1998/unknown}}
@article{item3-4, date={1999/open}}
@article{item3-10, date={2004-04-05T14:34:00}}
@article{item5-1, date={0000}}
@article{item5-2, date={-0876}}
@article{item5-3, date={-0877/-0866}}
@article{item5-5, date={-0343-02}}
@article{item5-8, date={1723~}}
@article{item5-9, date={1723?}}
@article{item5-10, date={1723?~}}
