Multi-user distributed applications running on heterogeneous networks must be able to display user interface components on several platforms. In wide-area public networks, such as the Internet, the mix of platforms and participants in an application will occur dynamically; the user interface will need to coexist with environments completely uncontrolled by the designer. We have dealt with this issue by considering user interfaces as a kind of document specifying the application's requirements and adopting SGML technology to process them locally. This approach provides new flexibility, with implications for the design of network browsers, such as those of the World Wide Web, and leads to an interesting class of active documents.
