Hi Brian,

Thanks for spotting this. The intention here is to behave in the same way as described in draft-ietf-anima-bootstrapping-keyinfra. I will take a note to correct this in the next version. BRSKI-AE is more targeting the data objects used for certificate enrollment but leaving base as is.

Best regards
Steffen
