Language: XQuery
Author: Dirk Kirsten <dk@basex.org>
Contributor: Duncan Paterson
Description: Supports XQuery 3.1 including XQuery Update 3, so also XPath (as it is a superset)
Refactored to process xml constructor syntax and function-bodies. Added missing data-types, xpath operands, inbuilt functions, and query prologs
