[regext] Signaling BCP support in EPP for
draft-ietf-regext-secure-authinfo-transfer and

"Gould, James" <> Mon, 16 March 2020 14:28 UTCShow header

One question that was raised by Patrick Mevzek on the mailing list was
associated with signaling the implementation of a BCP by the server that I
believe would also apply to the client.  This question applies to the two
REGEXT BCP drafts draft-ietf-regext-secure-authinfo-transfer and
draft-ietf-regext-unhandled-namespaces.  The only existing signaling mechanism
in EPP is the use of the greeting and login services.  A namespace URI could be
assigned for each BCP draft that is included as an <objURI> or an <extURI> in
the greeting to inform the client of the support of the BCP by the server, and
in the login command to inform the server of the support of the BCP by the
client.  Between the two options, I prefer the use of the <extURI>.  The
questions for the working group include:

  1.  Is signaling needed in EPP for the implementation of BCPs?
  2.  If signaling is needed:
     *   Will the existing signaling mechanism in EPP with the greeting and
     login services meet the purpose? *   Of the two service URIs <objURI> and
     <extURI>, which is the preferred URI to use? *   What URI scheme should be

                                                  i.      One proposal is to
                                                  include bcp in the namespace,
                                                  such as
                                                   The <version> would be
                                                  updated based on material
                                                  updates to the BCP draft and
                                                  bumped to 1.0 after WGLC.
