The Future of the DOM
For the moment, the DOM level 1 spec is limited to those methods that are needed for representing and manipulating structure and content.
Missing pieces that will be addressed in future levels of the DOM are as follows:
- • The interfaces for internal and external subsets
- • The ability to validate
- • The ability to control rendering via style sheets
- • The ability to control access
A lot of tool vendors will probably implement this API. Although the concrete language to be used (EcmaScript, VBScript, Java, and so on) can differ, you will always deal with the same objects with the same well-known properties and methods. This makes knowledge of the DOM a necessity.
