Ranges

As of September 10, 2009, we have added more extensive support for ranges.

Previously, range support was limited to date and month, thus you could express "January through March of 2007" (200701/200703), but not "January 1 through March 3 of 2007". This is now supported (20070101/20070303) and in addition, times, including timezone indicator, may be included at either end of the range. So the following now validate:

20050705/20050706
20050705T0715/20050705T0720
20050705T0715-0500/20050705T0720-0500
2005-07-05T07:15-05:00/2005-07-05T07:20-05:00
20050705T0715-0500/20050705T0720-0500
20050705T0715-0500/20050705T0720-0500
2004-01-01T10:10:10Z/2004-01-01T10:10:10+01:00
