If it's valid government ID, there could be some discretion, but we have taken it as a matter of air carriers having come to us saying, “Can you please be a little clearer? What is it?” We could have left it at “valid government-issued ID”, but in order to be helpful for people, people are asking us, “Can you please specify?” So that's what we've done.
If it's valid government-issued ID, then it's valid. That's what the regulation says.
