The date:leap-year function returns true if the year given in a date is a leap year. If no argument is given, then the current local date/time, as returned by date:date-time is used as a default argument.
The date/time string specified as the first argument must be a right-truncated string in the format defined as the lexical representation of xs:dateTime in one of the formats defined in [XML Schema Part 2: Datatypes]. The permitted formats are as follows:
If the date/time string is not in one of these formats, then NaN is returned.
