Validating xpath

validating xpath-65

The purpose of this document is to catalog the functions and operators required for XPath 3.1, XQuery 3.1, and XSLT 3.0 (at the time of writing, XSLT 3.0 requires support for version 3.0 of this specification, and makes support for version 3.1 optional).

The exact syntax used to call these functions and operators is specified in [XML Path Language (XPath) 3.1], [XQuery 3.1: An XML Query Language] and [XSL Transformations (XSLT) Version 3.0].

This document is governed by the 1 March 2017 W3C Process Document. This document was published by the W3C XML Query Working Group and the W3C XSLT Working Group, each of which is part of the XML Activity.

This Recommendation specifies XSLT and XQuery Functions and Operators (F&O) version 3.1, a fully compatible extension of F&O version 3.0.
