section 6.1.5 says:

   When BRSKI (see
   [I-D.ietf-anima-bootstrapping-keyinfra]) is used, the IPv6 locator of
   the BRSKI registrar from the BRSKI TLS connection SHOULD be
   remembered and used for the next renewal via EST if that registrar
   also announces itself as an EST server via GRASP (see next section)
   on its ACP address.

The BRSKI TLS connection is proxied through a join proxy.
The pledge (new node) never knows what the IPv6 locator of the BRSKI registrar is.
I suggest removing this paragraph, the node should listen for the EST GRASP
announcement.


6.1.5.3 mandates use of CRLs rather than OCSP.
I'm okay with that, but I wanted to make sure the WG understood.
OCSP might require a node to be on the ACP before it could get get on the
ACP.  CRLs could be cached for extended periods of time.

We might consider adding a CRL retrieval step to BRSKI, after the cacerts are
retrieved.
