By default, this is true. The following table shows how isRequired and isRepeatable map to the *, +, and ? qualifiers:

                         isRequired
                   ------------------------
    isRepeatable  |   true    |    false
    --------------|-----------|------------
            true  |     +     |      *
    --------------|-----------|------------
           false  |     --    |      ?

Note that the defaults of isRequired and isRepeatable map to the required/not repeatable (i.e. no operator) case.
