Advanced Relationship Classes
Description
Relationship Classes are just convenient groupings for the purpose of having related relationship types close to each other. They are grouped into classes here in the documentation, and in the drop-down list from which you select the relationship type.
In the drop-down list you find the classes in the first level fo the indented type listing. You cannot apply these first level elements as relationship types. They are really just classes: containers for elements that you can choose.
