Ah, I see. Since it’s not already in use I think the right thing to do is to request 1001 if it’s available, or another port number in the range if it’s not. I believe the problem for IANA is that it’s possible that 1001 will be assigned before this document gets published (by another document in the RFC Editor’s queue ahead of this one, for example). Let me run that by IANA and confirm.
