We allow the use of BaseDataType in Structure fields, Variable Values, Method Arguments and Event fields.

In Variable Values, Method Arguments and Event fields we allow to specify the Value Rank as -2 (any) if we want to allow scalar values and arrays for concrete values.

In fields of Structure DataTypes, we only allow -1 (scalar) or >0 (array or more dimensions). This is necessary for concrete DataTypes since they are directly embedded into the structure.

But fields of Structure DataTypes with BaseDataType are encoded as Variant. But a Variant can contain scalar values or arrays (one or more dimensions). Therefore this limitation is not necessary.

Especially in a structure like KeyValuePair, where the Value field is defined as scalar BaseDataType, I assume we want to allow also that the value contains an array e.g. an array of UInt32.

Is this valid?
If not, how can we allow this?
If yes, we are at least silent about this option.

This question also applies to the Body field of the UABinaryFileDataType
