ECMAScript for XML (E4X) Specification

ECMA has approved the ECMAScript for XML (E4X) Specification, which defines the syntax and semantics of a set of programming language extensions adding native XML support to ECMAScript:

E4X adds native XML datatypes to the ECMAScript language, extends the semantics of familiar ECMAScript operators for manipulating XML objects and adds a small set of new operators for common XML operations, such as searching and filtering. It also adds support for XML literals, namespaces, qualified names and other mechanisms to facilitate XML processing.

E4X goes back to a request by BEA in March 2003.
