Nir again: Sites should be based on HTML. CSS are very backward compatible. Write your pages like that: 1. round one: (required) write in HTML4.0 strict. (Then it looks fine on HTML 2.0+TABLES browsers and actually looks like HTML2.0 on HTML4.0 browsers) 2. round two: (optional) add stylesheets. (no change in backward compatibility) 3. round 3: (optional) add deprecated stuff to improve rendering in HTML 3.2 browsers (no problem with HTML 2.0 here) 4. Publish the pages! If you did in 3 only things that are done by the style sheet of 2, your work is also future compatible when the deprecated stuff become obsolete (50 years from now, given the widespeard usage of presentational markup). So what was the problem?

Use the NONETSCAPE element, and save lots of trouble :-) New non-HTML/non-XML features don't need new elements. OBJECT is generic. Its content gives the backward compatibility. (Possibly with nested OBJECTs) The NEWHTML proposal goes with the XML generic inclusion, this is "Under construction" in the respective working group. (Please, I am not on it!)
