   Hm, what is the purpose and use case that a required input allows a non-selection?
   So far this is the only example I know of where this is possible. So in the Processor it has to be intercepted extra if the List size is 0.
   
   For example, with requiredText it is not possible for the user to allow an empty string as input.
   In my eyes MultiValueSelection is the extension of SingleValueSelection and also here it is not allowed to have no selection.
