New versions of the Apache XML Project’s Xerces parsers released in June support the W3C XML Schema Recommendation. The new Xerces for Java supports essentially all of the XML Schema spec; Xerces for C++ implements a more limited subset of XML Schema, an incremental step toward complete support of the newly anointed specification that will in many cases take the place of DTDs in XML development. IBM also released updates to the alphaWorks parsers — XML4C and XML4J — that correspond to the Xerces parsers. A table outlines the XML Schema features supported in this release of the parsers.
