Rick Jelliffe at XML.com: "This article shows how to describe Wiki content using SGML. We use this technique to convert a Wiki page into XML using the open source SP software from James Clark. Using this technique, you can provide your users with low-keystroke ways to send structured data with less opportunity for sytnax errors and no reliance on the editing system at their end. The data does not need to be rich text, it could even be records of data."
