Leveled prerequisites

Within our documentation, we have rationalized the use of prerequisite elements to three different levels.

  1. Document related prerequisites, which apply to the whole document and are of basic type.
  2. Chapter related prerequisites, which apply to a chapter including its subchapters.
  3. Special prerequisites, which apply to a single Instruction list.

This way, we effectively reduce the information load onto our readers, without sacrificing important information.
