** Section 5.
   This document creates a registry called "EVPN ESI Label Extended
   Community Flags" for the 1-octet Flags field in the ESI Label
   Extended Community [RFC7432].
...
   In addition, the "Multihoming redundancy mode" field is initialized
   as follows:
...
   And the field "Split Horizon Type" is initialized as follows:
...
   New registrations in the "EVPN ESI Label Extended Community Flags"
   registry will be made through the "IETF Review" procedure defined in
   [RFC8126].

The above IANA guidance is ambiguous.

--  How many registries are being created – one or three?  The text explicitly
says that a registry named "EVPN ESI Label Extended Community Flags" will be
created.  However, the subsequent text says that "Multihoming redundancy mode"
and "Split Horizon Type" will be “initialized”?  Does “initialized” mean
registry creation?

-- If "Multihoming redundancy mode" and "Split Horizon Type" are new
registries, are they also following an IETF Review policy?  The text only says
that "EVPN ESI Label Extended Community Flags" uses IETF Review?
