0-n Cardinality Constraint

Hi Everyone,
Is there any way to restrict the cardinality to some variable m where 1<m<n
If yes how to do it?

Constant: value
constant: value

restrict its cardinality from 0...n to some user defined value

The Constraints aspect can be used to restrict the model beyond the settings in the structure.
E.g. the "can be parent" concept function:

concepts constraints Constants {
  can be child <none>
  can be root <none>
  can be parent
    (childConcept, node, childNode, operationContext, link)->boolean {
      node.constants.size < 3;
  can be ancestor <none>
  <<property constraints>>
  <<referent constraints>>
  default scope
    <no default scope>
