W3C Invites Implementations of XPath 3.1, XQuery 3.1, XQueryX 3.1

Today the XSLT Working Group and the XQuery Working Group jointly published Candidate Recommendations and invite implementation of XPath 3.1 and supporting documents. The XQuery Working Group published Candidate Recommendations and invites implementation of XQuery 3.1 and XQueryX 3.1. The supporting documents are XPath Functions and Operators; XQuery and XPath Data Model. XQuery 3.1 and XPath 3.1 introduce improved support for working with JSON data with map and array data structures as well as loading and serializing JSON; additional support for HTML class attributes, HTTP dates, scientific notation, cross-calling between XSLT and XQuery and more. The Serialization specification remains a Last Call Working Draft and was not republished, in order to improve JSON, map and array support in response to a Last Call Comment; it is expected to follow the other documents in the New Year.
