There are many specifications coming out of the W3C that, while being Internet oriented, have little or nothing to do with the World Wide Web. When Sun retracted Java from ECMA standardization, many people were pretty pissed off, but I was actually quite happy.
Standards bodies suck, plain and simple.
Maybe XML and related technologies need to be taken out of the hands of the W3C and given to a custodial group who isn't influenced by high-paying clientel. This site is using the Hazard Area Revisited theme.
