2008-11-26: The XML Core Working Group has published the W3C Recommendation of Extensible Markup Language (XML) 1.0 (Fifth Edition). This fifth edition of the widely deployed standard XML incorporates corrections to errata found in previous versions. In particular, one correction relaxes the restrictions on element and attribute names, thereby providing in XML 1.0 the major end user benefit currently achievable only by using XML 1.1. As a consequence, many possible documents that were not well-formed according to previous editions of this specification are now well-formed, and previously invalid documents using the newly-allowed name characters in, for example, ID attributes, are now valid. XML has been designed for ease of implementation and for interoperability with both SGML and HTML. Learn more about the Extensible Markup Language (XML) Activity. (Permalink)
