Mmmmm.... this is what I just read about Postel's robustness principle in http://www.joelonsoftware.com/ : """ Now there are all these web pages out there with errors, because all the early web browser developers made super-liberal, friendly, accommodating browsers that loved you for who you were and didn’t care if you made a mistake. And so there were lots of mistakes. And Postel’s “robustness” principle didn’t really work. The problem wasn’t noticed for many years. In 2001 Marshall Rose finally wrote: Counter-intuitively, Postel’s robustness principle (“be conservative in what you send, liberal in what you accept”) often leads to deployment problems. Why? When a new implementation is initially fielded, it is likely that it will encounter only a subset of existing implementations. If those implementations follow the robustness principle, then errors in the new implementation will likely go undetected. The new implementation then sees some, but not widespread deployment. This process repeats for several new implementations. Eventually, the not-quite-correct implementations run into other implementations that are less liberal than the initial set of implementations. The reader should be able to figure out what happens next. Jon Postel should be honored for his enormous contributions to the invention of the Internet, and there is really no reason to fault him for the infamous robustness principle. 1981 is prehistoric. If you had told Postel that there would be 90 million untrained people, not engineers, creating web sites, and they would be doing all kinds of awful things, and some kind of misguided charity would have caused the early browser makers to accept these errors and display the page anyway, he would have understood that this is the wrong principle, and that, actually, the web standards idealists are right, and the way the web “should have” been built would be to have very, very strict standards and every web browser should be positively obnoxious about pointing them all out to you and web developers that couldn’t figure out how to be “conservative in what they emit” should not be allowed to author pages that appear anywhere until they get their act together.
