Constrained Container RM-Types can define a "cardinality" for their list/array fields and the contained types can define "occurrences" for themselves inside the array. The summed max-"occurrences" may never surpass the max-"cardinality and the summed min-"occurrences" may never be less than the min-"cardinality". The min-max-"occurrences" could perhaps even be calculated from the "occurrences".
What information gain does the "cardinality" provide ?
Or what is the usecase where a given "cardinality" is needed, because the information is not already given by the all "occurrences" ?
