Component Model (aka XBL2) Use Cases

A canonical set of uses cases that represents the set of problems we are trying to solve by implementing a component model. For implementation details, see XBL2 Spec.

Built-in HTML Elements and Their Behaviors

  • provide a uniform way to browsers to implement complex HTML elements, such as video/audio, sliders, progress elements, etc. possibly using scripting.
  • provide light-weight implementations of specialized markup languages

Custom User Interface Widget System

Build a widget system that allows the following:

  • asynchronously instantiate and initialize widgets
  • for instance, display a widget without starting up a script context, then progressively enhance with script.
  • seamlessly reuse widget written using various libraries or frameworks
  • use widgets declaratively, with minimal knowledge of the underlying implementation
  • provide a uniform way (i.e. DOM) to declare widget APIs

Layout Manager

  • make easier the restructuring of content to accommodate layout, both in an imperative and a declarative way
  • enable development of templating/theming frameworks
