Hypertext functionalities with XML

Hypertext functionalities represent part of the distilled wisdom of the hypermediacommunity. Given the peculiar nature of the World Wide Web, it is very difficult to successfully propose functionalities that can become widely accepted. Yet, standards such as XLink may provide the needed basic tools to implement most of them. In this paper we briefly discuss the issues brought forth by the hypertext functionalities and introduce XMLC. XMLC is our prototype of an XML browser that, given its modular architecture and general scope, can be used as the basis for implementing sophisticated hypertext functionalities on the Web. Our own implementation of a seminal XLink support is further discussed.
