A posting from Henry S. Thompson (HCRC Language Technology Group, University of Edinburgh) announces an update of the W3C/LTG XML Schema Validator tool. The Validator for XML Schema REC (20010502) version is "an open source work-in-progress attempt at a conformant schema-aware processor, as defined by XML Schema Part 1: Structures, May 2, 2001 (REC) version. XSV has been developed by Henry S. Thompson and Richard Tobin of the Language Technology Group of the Human Communication Research Centre in the Division of Informatics at the University of Edinburgh." The new release [XSV 1.197/1.99 of 2001/07/06 10:02:16] is available interactively online from the W3C web site. The '2001/07/06' release provides bug fixes and better handling of attribute defaults. Source code and Win32 binaries have also been updated. The online version of the tool provides two HTML forms: (1) one for checking a schema which is accessible via the Web, and/or schema-validating an instance with a schema of your own, (2) another for file upload if you are behind a firewall or have a schema to check which is not accessible via the Web. Four styles of output may be selected (verbose/concise; styled for different generations of HTML browsers).
