W3C Invites Implementation of XPath 3.1; XSLT and XQuery Serialization 3.1

The XML Query Working Group and the XSLT Working Group invite implementation of the following Candidate Recommendations:

• XML Path Language (XPath) 3.1: XPath 3.1 is an expression language that allows the processing of values conforming to the data model defined in XQuery and XPath Data Model (XDM) 3.1. The data model provides a tree representation of XML documents as well as atomic values such as integers, strings, and booleans, and sequences that may contain both references to nodes in an XML document and atomic values.
• XSLT and XQuery Serialization 3.1: This document defines serialization of an instance of the data model as defined in XQuery and XPath Data Model (XDM) 3.1 into a sequence of octets. Serialization is designed to be a component that can be used by other specifications such as XSL Transformations (XSLT) Version 3.0 or XQuery 3.1: An XML Query Language.
