OK. It as KHTML and Webkit share a lot of code, I'd imagine Safari 
either already supports this, or is not far from doing it.

The "incremental loading is not supported" argument against XHTML is 
therefore on it's way to become a thing of the past.

Does anyone know since what version Opera and Konqueror started to 
support this?
