The first step given to separate concepts in web environments has been to take apart presentation from data. This split has been gotten due to the appearance of the Extensible Mark-up Language (XML) and the application of style sheets. The new ideas from the advanced separation of concerns community and the new abstractions like aspects make us think this original division isn?t rich enough. There are important concepts of Internet applications that should be defined separately. If we look at new web design methodologies, we can realize that one of these aspects is navigation. Following the way started by XML, we propose the use of the XML Linking Language (XLink) as a first stage to obtain the separation of the navigational aspect.
