Not all the chapters will be of interest to all readers. In some cases we describe and critique a standard in great detail. These chapters might not be of interest to students or people trying to get a conceptual understanding of the field. But in many cases the standards are written fairly unintelligi- bly. People who need to understand the standard, perhaps to implement it, or maybe even to use it, need to have a place where it is described in a readable way (and we strive for readability), but also a place in which mistakes in the standard are pointed out as such. It’s.
