The decision to ask to pay for Saxon in some way corresponds with sun's blogs entries regarding free software (see http://blogs.sun.com/jonathan/date/20090302). They, however, argue for a free software. I know that: saxon is really great software; and one cannot compare sun and saxoninca; and I'm not very profound in business side of development; Nevertheless I'd like to point to the idea that sun suggests: to get profit from services around software; In your case I can think of your great books, which among other things are based on saxon existence, and payable support.
