Validation of an array of strings (or other primitives)?

[skogowskinetfactory]

I see that DataCollection and DataCollectionOf will not work with simple primitives, ArrayType checks only keys, ListType only checks if property is an array.
Is there no way of checking if every element in an array is a string (and possibly more rules for that string?)

I figured this out myself.
It seems impossible to perform validation of arrays of primitives through attribute markings, but it is possible through the 'rules' method.
public static function rules()
