[Hannes Tschofenig <[e-mail]>]

Hi all,

I have a remark for the RD draft: Section 5.3 defines the registration procedure and indicates that the endpoint name is "mostly mandatory".

I would prefer it is defined as "optional". Section 8.1 highlights the security issues with using this unauthenticated identifier quite nicely. However, it comes up with a strange conclusion IMHO. Here is what it says:

"
   Therfore, Endpoints MUST include the Endpoint identifier in the
   message, and this identifier MUST be checked by a resource directory
   to match the Endpoint identifier included in the Registration
   message.
"

I would argue that under normal operation there is no reason to include the endpoint name since it is not authenticated and there will be a security protocol used (which offers authenticated endpoint identification). For this reason I would argue that the endpoint name has to be optional and I prefer that it is stated that it will be used only for debugging purposes or for those cases where the identifiers used in the security protocol are insufficient for endpoint identification.

Ciao
Hannes
