[Sis-dtn] NULL report-to EID in bundle primary block is ok?

I agree.  As an aside, I think "SHOULD reject" rather than "MUST reject" is important to retain for anonymous bundles.  Surely we'll never have any need for whistleblower communications in future space flight operations, but just in case we ever did, it would be convenient to be able to send a BIB-authenticated whistleblower message as the payload of an anonymous bundle, where the payload is encrypted in the public key of the intended confidential recipient.

Bob, Ed, Felix,

    May be accepted was my understanding as well.  From a security aspect, we also agreed that policy could override and reject any anonymous bundles. I would assume that reject was the default.

Kind regards,
