I'm falling asleep as I type DocBook XML 4.12 QuickStart Guide. That's right its an even numbered version. It's stable. I've even removed all of the harmless errors I was getting when compiling. Plus, the format now checks out with emacs xml-mode. Thus, you can use all the handy menus and syntax checkers to write your docs. I've actually been playing around with XML + XSL instead of DSSSL. The XML tranformations processor I tried first sabletron just doesn't seem to be able to do the DocBook style sheets. I'll try one of the more tried and tested java based processors next.
