Type of array elements in instantiated struct is not set

[maxhoerstr]

If a struct is instantiated, for example in a Service call, the struct can contain an array. This array has no information about the type of its elements. For simple datatypes like number or string, it can be set through the values of the array. If the values of the array are also structs, which has to be instantiated too, it is not known to which struct defintion they belong.
It could be set in the semantic validation when the Struct instances are checked.
