[sidr] Expected protocols in rpki-rtr

[Paul Hoffman <[e-mail]>]

Greetings again. Section 7 of draft-ietf-sidr-rpki-rtr-14 has a list of supported transports. However, it does not list the one that some people have said that they expect it to be run under sometimes, namely bare TCP. If we all know that this is likely to be the case, we should have it listed in the document. I propose the following for the end of section 7, just before 7.1:

   Caches and routers MAY use unprotected TCP as a transport,
   even though this provides none of the security protections of
   the other protocols listed here. Unprotected TCP MUST only be
   used when there is other forms of trusted security in place.

Of course, we can also just ignore the fact that many users want to do this, but being honest in the document might be better than pretending otherwise.
