LOOKING TO PROMOTE interoperability on the Web, the World Wide Web Consortium (W3C) this week released its XML 1.0 (Second Edition) W3C Conformance Test Suite, to enable developers to test an XML processor, or parser, for conformance with the W3C XML 1.0 (Second Edition) recommendation. Developed with the National Institute of Standards and Technology (NIST), the suite contains more than 2,000 test files and provides a set of metrics for determining conformance to the XML specification recommendation. Developers can download W3C XML conformance test suites for free at www.w3.org/XML/Test . A W3C spokesperson said the suite contains no significant new features but has clarifications of the specification. The suite formerly was hosted by the Organization for Advancement of Structured Information Standards (OASIS). Software Development
