Let's not get carried away. The RFC says the following:

   1.2.3. User Agents

   An HTML user agent conforms to this specification if:

        * It parses the characters of an HTML document into data
        characters and markup according to [SGML]. 
        
        ...

It does not specify what the UA must do in cases of invalid input. Within
certain limits, the UA can do anything its author wants to do.

I suggest that a conformance clause is missing from the W3C draft, and that
it should be at least as strong as the RFC.
