Complexity Of Conditional Sections

Conditional sections are another SGML invention that got into XML because the people on the committee who had experience writing DTDs claimed that life would just be impossible without them.

Unless you're going to be either writing a validating parser, or designing a lot of DTDs, you really can skip this section. In the latter case, a better way to learn about this stuff is to read one of the excellent books on the subject.
