W3C Invites Implementations of XQuery and XPath Full Text 3.0; Supporting Requirements and Use Cases Draft Updated

The XML Query Working Group and the XSLT Working Group invite implementation of the Candidate Recommendation of XQuery and XPath Full Text 3.0. The Full Text specification extends the XPath and XQuery languages to support fast and efficient full text searches over arbitrarily large collections of documents. This release brings the Full Text specification up to date with XQuery 3.0 and XPath 3.0; the language itself is unchanged.

Both groups also published an updated Working Draft of XQuery and XPath Full Text 3.0 Requirements and Use Cases. This document specifies requirements and use cases for Full-Text Search for use in XQuery 3.0 and XPath 3.0. The goal of XQuery and XPath Full Text 3.0 is to extend XQuery and XPath Full Text 1.0 with additional functionality in response to requests from users and implementors.
