We are going to change this field in the header to "SensorDescription" to be more consistent with the examples in the specification. The header line is provided as a helpful guide and is not strictly needed for parsing the fixed-field data content. Nevertheless, someone might parsing this header.
If you will be effected by this change and cannot modify your usage to accommodate it quickly or easily please let us know so we can coordinate a time frame for the change. If we do hear from anyone the change will go into the next release, likely this week or next.
