The aim of the WDG DTD is to promote maximum accessibility and browser compatibility, without breaking existing technologies. Our first (and currently only) DTD is wdg-compat.dtd, which is designed for maximum back-compatibility, and offers full support for complementary WWW technologies such as CSS Stylesheets for presentation and JavaScript/ECMAScript for embedded programming.
