yes, we are at least silent about this option, and we don't think we need clarification.

Clarify in Part 3 that ValueRank of -2 is allowed for a StructureField of BaseDataType.

Clarify its use in Part 5 Key/Value pair construct.

Clarify UABinaryFileDataType in Part 14.

Notation for ValueRank -2 is ([])

changed the description of the valueRank to

"The value rank for the field.
It shall be Scalar (-1) or a fixed rank Array (>=1). When the dataType is baseDataType it shall be Scalar (-1), a fixed rank Array (>1) or Any(-2)."

In the Erlangen F2F we agreed that BaseDataType implies the value can contain any DataType with any ValueRank and that we just need a clarification in Part 3.

Matthias will provide a proposal for clarification in Part 3.

Status after Erlangen F2F:

The change for valueRank in StructureField must be reverted.

A clarification should be added to 8.7 BaseDataType.
But the group did not agree on the clarification yet.

Matthias prepared the following two text proposals but they need further discussion:

Option 1:
A value based on a BaseDataTye is a container that can contain any DataType and any ValueRank. In places where the BaseDataType is used as part of a DataType and ValueRank definition, the ValueRank defines the ValueRank of the container.

Option 2:
If the BaseDataType is used as DataType with ValueRank scalar in Variables, Event fields, Methode Arguments or Structure fields, the concrete instance of the value can be of any DataType with any ValueRank. If the ValueRank is array or multi-dimensional arrays, this applies to all elements in the array.

Here is the proposal for clarification in 8.7 BaseDataType

A value based on a BaseDataTye is a container that can contain any DataType and any ValueRank. In places where the BaseDataType is used as part of a DataType and ValueRank definition, the ValueRank defines the ValueRank of the container.

If the BaseDataType is used as DataType with ValueRank scalar in Variables, Event fields, Methode Arguments or Structure fields, the concrete instance of the value can be of any DataType with any ValueRank. If the ValueRank is array or multi-dimensional arrays, this applies to all elements in the array.

Added suggested clarifying text to section 8.7.

Agreed to text completely re-written in telecon.
