The Unused_tags.txt file lists all tags that are not on any graphic and not in the specialized lists.
The basic concept of unused was created to mean that the tag did not appear on any graphic. This has been improved to also require that the tag not have a Primary Display or Alarm Vector entry. The Primary Display and Alarm Vector entries allow a chosen display to be called up from the operator console alarm summary, so we treat the tag as being "used", even though it does not appear on a graphic.
For example:
