This document surveys a group of market-leading widget user agents with the aim to inform the requirements of the Widgets 1.0: Requirements document. The survey exposes commonalities and fragmentation across widget user agents, and discusses how fragmentation currently affects, amongst other things, authoring, security, distribution and deployment, internationalisation and the device-independence of widgets. The document concludes by making a set of recommendations on what aspects of widgets require standardization to reduce fragmentation to ultimately standardize a cross-platform widget solution.

This practical guide provides you with the knowledge required to effectively use the XML Binding Language 2.0. It introduces both the basic and advanced concepts of XBL and describes its syntax and scenarios that should be considered best-practice. It also describes the purpose of the language elements described in the XBL 2.0 specification.

XBL describes the ability to associate elements in one document with script, event handlers, styles, and more complex content models in another document. You can use XBL to re-order and wrap content so that, for instance, simple HTML or XHTML markup can have complex CSS styles applied without requiring that the markup be polluted with multiple div elements. In addition, if you are a programmer, you can use XBL to implement new DOM interfaces, and, in conjunction with other specifications, it enables arbitrary XML tag sets to be treated as "widgets" (pluggable user interface components).
