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).
