Yes, it would be possible. But, for security reasons, In-Data-Packet OAM me= thods, such as Alternate-Marking and IOAM, should be applied to limited/con= trolled domains. You can find more details about this requirement in RFC 93= 41 and RFC 9197. It was initially discussed in RFC 8799.

This should be possible, but is not very deeply explored? (Or maybe I'm just missing the point, and the remarks on encapsulating traf= fic cover this sufficiently?)
