Name
xs:gYearMonth — Period of one month.
Facets:
xs:enumeration, xs:maxExclusive, xs:maxInclusive, xs:minExclusive, xs:minInclusive, xs:pattern, xs:whiteSpace
<xs:simpleType name="gYearMonth" id="gYearMonth">
<xs:restriction base="xs:anySimpleType">
<xs:whiteSpace value="collapse" fixed="true"/>
</xs:restriction>
</xs:simpleType>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).
