Hello David & all,

Because you are not submitting this registration request as an RFC, I 
would recommend moving some of the information from the "Introduction" 
section of the document into the "Purpose" section of the completed 
registration template.

In my opinion it would also be useful to include a few examples of UIC 
URNs, as well as a link to documentation (if any) on the uic.org website 
about assignment processes and procedures.

However, these suggestions are not blockers for me to voice approval for 
the registration request.

Lars and Stephanie, do you have feedback as well?

Peter

Unfortunately RFC 3406 itself is not marked as obsolete, although the procedure described in it has been replaced by the one outlined in RFC 8141 (which obsoletes both RFC 2141 and 3406).

Although these two registration templates are quite similar, RFC 8141 template does require a Security and privacy section, which should "describe any potential issues related to security and privacy with regard to assignment, use, and resolution of names within the URN namespace". See clause 6.4.4 of RFC 8141 for more information.
