The XSL Challenge

Friday May 21st, 1999

C. David Tallman has news of an interesting article at In it, Michael Leventhal of CITEC (the group creating DocZilla) takes off the gloves and challenges XSL to best XML/CSS/DOM in a competition of functionality/usability in the web application space. Interestingly, Mozilla plays an important role in the contest. From

"Anything XSL can do in the Web environment, I can do better using technologies supported by current W3C Recommendations. Of course, what is 'meaningful' in the Web environment is open to a variety of interpretations. Therefore, the subject of the challenge should be one that the XSL camp and I agree is meaningful. I am also ready to make this bet a little bit more than an academic exercise. If I lose, I will pledge that I, and my crack mozilla development team, will assist in implementing XSL in the mozilla open source project. If my opponents lose they will agree to desist from XSL advocacy, vote against an XSL Recommendation if they are members of the W3C, and will join me in calling for full, flawless, and unequivocal vendor support of CSS1 and CSS2, DOM Level 1, and XML 1.0 as the very first and top priority of the web community."

> The XSL standard is broken into two halves, the XSL transformation language and the XSL Formatting Objects. XSL-T has generated a lot of excitement with developers, whereas XSL-FO has generated a lot of excitement with marketing morons.

As you know, I don't share your excitement about XSLT although I do understand the reason for it. On the other hand we agree about XSL-FO. A world in which we had XSLT and not XSL-FO is a world I would not find ideal but I could certainly live in it. I hope that people like you will raise your voices loud and clear for totally separating and removing an dependency between XSLT and XSL-FO so at least the latter can languish as it deserves.
