This is a talk given by Liam Quin, at Extreme Markup in Montreal in August 2002, as a daily polemic.
The talk was projected onto a large screen with 640x480 resolution; I have added these notes afterwards.
Disclaimer: although I am the W3C XML Activity Lead, this talk does not represent the consensus or opinions of any W3C working group, nor of any individual. In fact, it's just my opinions. That's why it's the daily polemic.
There is also a published paper, XMLR: XML Reduced.
