Name
xs:gMonthDay — Recurring period of time: yearly day.
Facets:
xs:enumeration, xs:maxExclusive, xs:maxInclusive, xs:minExclusive, xs:minInclusive, xs:pattern, xs:whiteSpace
<xs:simpleType name="gMonthDay" id="gMonthDay">
<xs:restriction base="xs:anySimpleType">
<xs:whiteSpace value="collapse" fixed="true"/>
</xs:restriction>
</xs:simpleType>Description
The value space of xs:gMonthDay is the period of
one calendar day recurring each calendar year (such as the third of
April); its lexical space follows the ISO 8601 syntax for such
periods (i.e., " -- MM-DD”) with
an optional timezone.
When needed, days are reduced to fit in the length of the months, so
--02-29 would occur on the the 28th of February of
nonleap years.
Restrictions
The period (one year) and the duration (one day) are fixed, and no calendars other than the Gregorian are supported.
Example
Valid values include "--05-01",
"--11-01Z", "--11-01+02:00",
"--11-01-04:00", "--11-15", or
"--02-29".
The following values would be invalid: "-01-30-"
(the format must be "--MM-DD"),
"--01-35" (the day part is out of range),
"--1-5" (the leading zeros are missing), or
"01-15" (the leading "--" are
missing).
