This item is a readout only and includes no measurement.
This metadata element is best effort metadata. If the detected value is a distinguished value, the search shall be continued until a non-distinguished value is found. If no non-distinguished value is found, the distinguished value shall be used.
If the metadata appears more than once in the file, the results can be output using the implicit Track and/or WrapperLocator output attributes.
