1 Introduction

This document describes the namespace http://www.w3.org/2005/XQueryX defined by the [XQueryX 3.1] specification (October 2014 version). This namespace is typically identified by the namespace prefix xqx:, which is not a predefined prefix. For updated information, please refer to the latest version of the [XQueryX 3.1] specification.

This document contains a directory of links to related resources, using RDDL (as defined in [Resource Directory Description Language (RDDL)]).

It is GRDDL-enabled (as defined in [Gleaning Resource Descriptions from Dialects of Languages (GRDDL)]), that is to say that a GRDDL-compliant processor can extract useful RDF (as defined in [Resource Description Framework (RDF): Concepts and Abstract Syntax]) representations of the information contained herein.

2 XML Schema

There are two syntaxes in which [XQuery 3.1] queries can be written. One is the so-called human-readable syntax defined by [XQuery 3.1], while the other is an XML syntax for XQuery defined by [XQueryX 3.1].

XQueryX, as defined in [XQueryX 3.1], is specified in the namespace http://www.w3.org/2005/XQueryX, which is defined by an XML Schema.

This schema specifies the XML syntax of the XQuery expressions defined in [XQuery 3.1]. It is located at http://www.w3.org/2014/10/XQueryX/xqueryx.xsd.

XQuery 3.1 queries written using the XML syntax must be valid according to that schema. Validation must be performed as defined by [XML Schema Part 1: Structures Second Edition], using strict validation, full validation attempted, using the <xqx:module> element as the validation root. The result of that validation must not be invalid or notKnown.

3 XSLT Stylesheet

Queries written using the XML syntax of [XQuery 3.1] have semantics that are defined by the XQuery "human-readable" syntax that results from transforming those XML syntax queries using the stylesheet located at http://www.w3.org/2014/10/XQueryX/xqueryx.xsl.

XQueryX 3.1 (1 October 2014 version)

This document describes the names that are defined in this namespace at the time of publication. The W3C reserves the right to define additional names in this namespace in the future. [XQueryX 3.1] is the only specification that is permitted to amend this namespace. It may, however, be augmented by other specifications that define XQueryX 3.1 extensions corresponding to XQuery 3.1 extensions.
