Today, the W3C announced the standardization of the Efficient XML Interchange (EXI) format, version 1.0. The EXI standard dramatically improves the performance, network efficiency, and power consumption of applications that use XML. EXI is a very compact representation of XML information, making it ideal for use in smart phones, devices with memory or bandwidth constraints, in performance sensitive applications such as sensor networks, in consumer electronics such as cameras, in automobiles, in real-time trading systems, and in many other scenarios.
