Basic DSSSL
You have already seen some of DSSSL in practice. Now it's time to cover some of the theory. Bear with me; once you get into the theory DSSSL can be very hard to explain and even harder to understand. Don't worry, though; even if you only partially understand what follows you should still grasp enough to build some extremely powerful style sheets. If it all seems too abstract, don't worry either-I'll conclude this chapter with several more practical examples that you can mimic or just copy.
