IBM alphaWorks has released an updated version of the XML Parser for Java (XML4J) which supports the W3C XML Schema specification and includes other enhancements. XML4J version 3.2.0 is distributed as source code and as a binary; it is covered by the standard Apache 1.1 license. XML4J now incorporates the following: "(1) W3C XML Schema Recommendation 1.0 support; (2) SAX 1.0 and SAX 2.0 support; (3) Support for DOM Level 1, DOM Level 2, and for some features of DOM Level 3 Core Working Draft; (4) JAXP 1.1 support." The IBM XML applications development team has also released an improved version of the 'XML Schema Quality Checker' tool. Version 1.85 of the XML Schema Quality Checker fixes 15 bugs present in the previous version, and improves usability under Solaris 2.7 and Windows 98. IBM's XML Schema Quality Checker "is a program which takes as input an XML Schema written in the W3C XML schema language and diagnoses improper uses of the schema language; where the appropriate action to correct the schema is not obvious, the diagnostic message may include a suggestion about how to make the fix."
