We actually never use extended information when normally using the ViewInformation2D. The exception here is when we construct it from property values, where the unknown property values are then stored into the extended information sequence and then later reconstructed when we convert it back to a sequence of property values. Just for that case we don't neeed to expose the extended information to the outside and create it, as that is then a implementation detail for the UNO use case. I am also not convinced we need it when creating ViewInformation2D with the sequence of property values - it certantly not expected that we need to preserve the property values at all, but that is something that needs to be checked.
