I have no idea why you rule out "CAS GUI authoring systems", which I suspect is a category into which you include Mathematica. Mathematica is far more than a "CAS GUI authoring system", as evidenced by our publicon product which has nothing to do with computer algebra, numerical calculation, graphics, or for that matter "technical computing" which is the market that Mathematica serves. Mathematica V4 generates HTML w/MathML, both from what you type and what is computed by the system. It does not directly support DocBook, but can be made into a very good DocBook w/MathML authoring system with some work: 1. Create a style sheet that corresponds to the styles/tags allowed in DocBook. Depending on how fancy you want the styles to be shown, this will take a few hours to a couple of days. 2. Write a program to convert the notebook to XML/DocBook. This is essentially an syntactic transformation and is very simple. An experienced Mathematica user could do this in less than an hour (I know someone who did this sort of thing in 15 minutes). Someone who only uses Mathematica occasionally would probably spend a few hours on this. 3. Start writing documents using the DocBook stylesheet created in '1'. Wolfram Research plans to release style sheets for the major XML DTDs when it becomes clear what are the major DTDs. Until then, you have to create your own style sheet, or check on MathSource to see if someone else has contributed one.
