No, one of the major benefits of using WDDX is that programmers can exchange structured data over the Web without having to use the XML natively. Currently, the WDDX SDK provides modules for JavaScript 1.x, ColdFusion 4.0, COM, Perl and Java. Allaire does not plan to implement modules for other languages, but using the SDK, any developer will be able to build a module for any language platform that can support the core WDDX data types. Date-time values are encoded according to the full form of ISO8601. Timezone information will be successfully parsed and used to convert to a local date-time value.
Arrays are integer-indexed collections of objects of arbitrary type.
Structures are string-indexed collections of objects of arbitrary type. In many languages they are known as associative arrays. Only simple data types can be stored in recordsets. WDDX.org, with open distribution for major language environments. The primary way developers would use WDDX with browser-based applications is using the JavaScript 1.x implementation.
