/** Class holding information and utilities for handling different DN components, CN, O etc
 * 
 * This is a very complex class with lots of maps and stuff. It is because it is a first step of refactoring the DN/AltName/DirAttr handling. 
 * This previously consisted of lots of different arrays spread out all over the place, now it's gathered here in order to be able to get a view of it.
 * The underlying implementations have not changed much though, in order to still have things working, therefore there are lots of different maps and arrays, with
 * seemingly similar contents.
