Abstract
This paper deals with two aspects of virtual world creation - consistency of data and isolation of independent concepts. These concepts include among others 3D graphics rendering, physical simulation, audio processing, or user interaction. Current systems for virtual world creation focus more on concrete concepts and less on their independence thus limiting extensibility. They usually define static core functionality that quickly becomes outdated due to the fast development in computer industry. Adapting XML on the other hand focuses on extensibility, defining rules for cooperation (data sharing) and providing mechanisms for concept isolation. This makes it suitable as the base layer for extensible virtual world languages.
