Implementing it is not feasible. * It would cause a massive DDoS attack on www.w3.org. * It would make www.w3.org a single point of failure for the Web. * It would be bad for XML parsing performance. * It would break compatibility with existing content (IIRC MIT courseware, for example) that refers to a DTD that is not namespace- well-formed (i.e. has colons in PI targets). * New documents authored with the assumption that DTDs get fetched would break very ungracefully in existing Gecko and WebKit instances. http://hsivonen.iki.fi/no-dtd/ -- Henri Sivonen hsivonen@iki.fi http://hsivonen.iki.fi/
