 Where a role called 'CTO' is the highest ascendant, and 'A' is the lowest descendant. In a top-down role hierarchy, privilege increases as we descend in the tree.  So a person with role 'A' inherits all that are above.
 
 In describing a range of roles, begin range is the lowest descendant in the chain, and end range the highest. Furthermore a bracket, '[', ']', indicates inclusiveness, whereas parenthesis indicates exclusiveness for a particular endpoint.
