1. Document Object Model Requirements

1.5 Event Model [After Level 1]

The event model must be rich enough to create completely interactive documents. This requires the ability to respond to any user action that may occur on the document. Therefore, many of these requirements only apply if a UI component is involved.

1. All elements will be capable of generating events.
2. There will be interaction events, update events, and change events.
3. The event model will allow responses to user interactions.
4. The event delivery mechanism will allow for overriding of default behavior.
5. Events will bubble through the structural hierarchy of the document.
6. Events are synchronous.
7. Events will be defined in a platform independent and language neutral way.
8. There will be an interface for binding to events.
