XQuery and XPath Full Text Namespace Document

1 Introduction

This document describes the namespace http://www.w3.org/2007/xpath-full-text defined by the [XQuery and XPath Full Text 3.0] specification ( version). This namespace is typically identified by the namespace prefix xqxft:, which is not a predefined prefix. For updated information, please refer to the latest version of the [XQuery and XPath Full Text 3.0] 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 Schemas

There are two syntaxes in which [XQuery and XPath Full Text 3.0] queries can be written. One is the so-called human-readable syntax defined by [XQuery and XPath Full Text 3.0] as an extension to the syntax defined in [XQuery 3.0], while the other is an XML syntax for XQuery defined by [XQuery and XPath Full Text 3.0] as an extension to the XML vocabulary defined in [XQueryX 3.0].

XQueryX, as defined in [XQueryX 3.0] 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 3.0]. It is located at http://www.w3.org/2014/04/XQueryX/xqueryx.xsd.

The XML syntax defined in [XQuery and XPath Full Text 3.0] is specified in the namespace http://www.w3.org/2007/xpath-full-text, which extends the XML vocabulary defined in the namespace http://www.w3.org/2005/XQueryX. It is defined by a pair of XML Schemas.

The first of those two schemata specifies the XML syntax of the XQuery and XPath Full Text expressions defined in [XQuery and XPath Full Text 3.0]. It is located at http://www.w3.org/2015/08/xpath-full-text/xpath-full-text-30-xqueryx.xsd.

The second of those two schemata redefines components of the XML Schema defined in [XQueryX 3.0] as needed by the syntax defined in [XQuery and XPath Full Text 3.0]. It is located at http://www.w3.org/2015/08/xpath-full-text/xpath-full-text-30-xqueryx-redef.xsd.

XQuery and XPath Full Text 3.0 queries written using the XML syntax must be valid according to those two schemas. 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 Stylesheets

Queries written using the XML syntax of [XQuery 3.0] 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/2014/04/XQueryX/xqueryx.xsl.

This stylesheet extends the stylesheet defined in [XQueryX 3.0] that is located at http://www.w3.org/2014/04/XQueryX/xqueryx.xsl.
