Norm Walsh never ceases to amaze me. Not only has he created a very useful content model in a variety of flavors, plus stylesheets to do useful things with that content, he has now brought us DocBot!
Norm added a bot to #docbook. DocBot will answer a few stylized questions about DocBook, and I think will be a nice online help addition for our internal knowledge engineers, who are creating support articles based on Simplified DocBook.
Take a look at Norm's posting on the subject at: http://norman.walsh.name/2004/06/14/apis
