Obsolescence notices on old specifications, again

Hi all,

The recent message to www-dom about DOM2HTML [1] made me realize that we 
still haven't added warnings to obsolete DOM specifications to hopefully 
avoid that people use them as a reference.

I propose that we add a pointer to the contemporary specification to the 
following specifications:

* DOM 2 Core (DOM4)
* DOM 2 Views (HTML)
* DOM 2 Events (D3E)
* DOM 2 Style (CSSOM)
* DOM 2 Traversal and Range (DOM4)
* DOM 2 HTML (HTML)
* DOM 3 Core (DOM4)

and a recommendation against implementing the following specifications:

* DOM 3 Load and Save
* DOM 3 Validation

Hearing no objections, I'll try to move this forward.
