NB these client-side demonstrations contain platform dependencies - they were written for MS Internet Explorer 5.0, and will probably need to be modified to work with other browsers (including other versions of IE).
The configuration of this server is such that the files used in the demonstration cannot be served unmodified (they would be processed by Cocoon, but there would be compatibility problems). Therefore the files are provided as a ZIP archive which may be downloaded and run locally. Just decompress the files, and open index.html in IE 5.0. Expect problems if you use any other browser!
