Via webgraphics, a link to an announcement announcing ECMAScript for XML (E4X) (PDF) that I've mentioned a few times.
Geneva, 28 March 2003: ECMA International (ECMA) is completing extensions to the widely used ECMAScript standard, currently being updated to its 4th Edition. The enhancements known as E4X (ECMAScript for XML) standardize the syntax and semantics of a general-purpose, cross-platform, vendor-neutral set of programming language extensions adding native XML support in ECMAScript.
E4X will make it easier for Web developers to use the power of XML structured data, allowing them to leverage their existing skills and knowledge, and reuse familiar concepts, operators and syntax. E4X will also reduce code complexity, time to market and revision cycles, decrease current XML footprint requirements and enable looser coupling between code and external data.
Given the rising popularity of XML and the near universal usage of ECMAScript on the World Wide Web, the Web development community will welcome a simple, familiar, general purpose programming model for XML allowing them to harness the power and flexibility of XML immediately with little or no additional training.
Make sure you check out the only article I know of that explains this stuff.
Update: Here's a discussion on LtU and some documentation for this stuff.
