CeremonyLayoutSettings.IFrame

At first glance, it doesn't appear that there is any difference, one way or the other. I will see if I can figure out exactly what this setting does. I will let you know what I find.

It appears that this was a setting that only indicated if a package was meant to be displayed in an iframe or not. It changes nothing about the ceremony. Someone might use it as an indicator to make sure a package they are trying to embed was in fact intended to be embedded. I am told that this setting has been earmarked for removal.
