That value (0) works for me. In rfc8068bis, we need to clarify that the defined bits (UGNv...) are part of the Encapsulations field, and create a registry. [AR] Given that we have enough bits, my personal preference would be to reserve a bit to signal “No Encapsulation”. See also answer below. Question: the definitions of the bits say that they "can accept...encapsulation", which sounds to me like multiple encapsulations can be indicated. Is that ok, or should we enforce only one bit set at a time? [AR] I think we should allow to signal multiple possible encapsulations, thus multiple bits might be set at a time. This is a reason to reserve a bit for “No Encapsulation”.
