Construct a date value from an item value.
xs:date(item $value) => date
This is a constructor function that takes an item value as argument and
returns a value of type xs:date. 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

Schema Part 2: Datatypes, a value of type xs:date
represents a Gregorian calendar date as defined in ISO 8601. The lexical form
is CCYY-MM-DD where "CC" represents the century, "YY" the year, "MM" the month
and "DD" the day. You may not truncate digits on the left side. To represent a
date before Christ, you must prepend a minus sign.
