webstandards.org: "an article in ibm's development zone claims this [ie. xhtml 2.0's] lack of backward compatibility is actually a good thing".

excuse me, but where the hell are you heading for with xhtml 2.0? xlink, xforms and even xframes(!)... not to mention the <line> tag but i think this all is ugly crap.

i start to believe that not only sending but also generally using xhtml as html output is to be considered harmful.
