Yes, it’d be nice if everyone kept up to date on the progress of the various W3C working groups. They don’t. There are a lot of people who asked what professional markup looked like and were told (right or wrong) that XHTML was the future. So they went ahead and learned XHTML, built their websites and chose watching a DVD or spending time with their kids over watching Mark Pilgrim and Sam Ruby do battle over Postel’s Law. Now all of a sudden they’re told XHTML is dead. Some wailing and gnashing of teeth is to be expected. What’s needed is less “boy aren’t I smarter than them” snideness, and more Hey, here’s what’s up.

Draconian failure on error is not the answer problems of Postel’s law. Draconian error handling creates an unstable equilibrium in Game Theory terms —it only lasts until one player breaks the rule. One non-Draconian XML5 implementation in key client product and the Draconian XML ranks would break. Well-specified error recovery is the right way to implement the liberal part of Postel’s law.
