Syntax

xs:gDay(item $value) => gDay

Description

This is a constructor function that takes an item value as argument and returns a value of type xs:gDay. If the argument is a literal, then the literal must be a valid lexical form of its type.

As specified in the respective section of the W3C recommendation XML Schema Part 2: Datatypes, a value of type xs:gDay represents a recurring Gregorian day as defined in ISO 8601. The lexical form is ---DD, where "DD" denotes the day. You can append an optional time zone identifier. You may not omit any of the dashes in front.

Argument

$value	item value

Example

This query generates valid values of type xs:gDay:
```
xs:gDay("---27")
```
```
xs:gDay("---27Z")
```
```
xs:gDay("---27+01:00")
```
The last two queries use optional time zone identifiers: "Z" denoting UTC, and "+01:00" one hour ahead UTC.
