I had already experimented with such a features, but had not full decided
for a satisfactory design. Currently I only differenciate between
mandatory or not mandatory.
Giving the maximum number of occurencies seems very reasonable. With
minimum: It seems very rare that an option is required 'at least 3 times'.
But I might be wrong here. I will probably extend the mandatory mechanism
to cover such cases.
