Description

The value space of xs:gYearMonth is the period of one calendar month (such as the month of February 2002); its lexical space follows the ISO 8601 syntax for such periods (i.e., “YYYY-MM”) with an optional timezone.

Restrictions

The duration (one month) is fixed, and no calendars other than the Gregorian are supported.

Example

Valid values include "2001-10", "2001-10+02:00", "2001-10Z", "2001-10+00:00", "-2001-10", or "-20000-04".

The following values would be invalid: "2001" (the month part is missing), "2001-13" (the month part is out of range), "2001-13-26+02:00" (the month part is out of range), or "01-10" (the century part is missing).
