text{* In our scenario, content has three different types of addressees: 
\<^item> the @{emph \<open>examiner\<close>}, i.e. the author of the exam, 
\<^item> the @{emph \<open>student\<close>}, i.e. the addressee of the exam, 
\<^item> the @{emph \<open>validator\<close>}, i.e. a person that checks the exam for
  feasibility and non-ambiguity.

Note that the latter quality assurance mechanism is used in many universities,
where for organizational reasons the execution of an exam takes place in facilities
where the author of the exam is not expected to be physically present.
