I meant HTTP but I have to admit it was not clear. What I had in my mind when I wrote that was there needs to be something that forces people to provide semantics of web pages. By which I mean HTTP is too liberal, allowing any kind of document including documents without semantic annotations to be transferred. Therefore I thought people would provide page semantics if HTTP required documents be annotated with semantics just like HTTP requires Content-Type be given.
