XPath and XQuery Functions and Operators 3.0 (renamed from XPath and XQuery Functions and Operators 1.1 to align with the family of "3.0" specifications) defines a library of functions available for use in XPath 3.0, XQuery 3.0, and XSLT 3.0. Some of the new features since XPath 2.0 and XQuery 1.0 Functions and Operators include:

• More than 30 new functions have been added, including functions transferred from the XSLT 2.0 specification into Functions and Operators 3.0 and additional versions of existing functions with different signatures
• The syntax for regular expressions was enhanced to allow for non-capturing groups; additionally, a new flag value was added for regular-expression-related functions that accept a flag argument
• Support for function items has been added in the form of a number of new functions
• The description of fn:error was rewritten to accommodate the addition of try/catch capabilities in XQuery 3.0

This document defines constructor functions, operators and functions on the datatypes defined in [XML Schema Part 2: Datatypes Second Edition] and the datatypes defined in [XQuery 1.0 and XPath 2.0 Data Model]. It also discusses functions and operators on nodes and node sequences as defined in the [XQuery 1.0 and XPath 2.0 Data Model]. These functions and operators are defined for use in [XML Path Language (XPath) 2.0], [XQuery 1.0: An XML Query Language] and [XSL Transformations (XSLT) Version 2.0] and other related XML standards. The signatures and summaries of functions defined in this document are available at: http://www.w3.org/2005/xpath-functions.
