Thank you, Bill, for bringing RFC 4151 to our attention.  Helen, the author of the drafts in question, also agrees that the ‘tag’ scheme addresses the need.  

Given these circumstances, we consider the matter settled and, contrary to the NETMOD 97 minutes, we will not issue a call for adoption for draft-chen-rdns-urn and draft-chen-netmod-enterprise-yang-namespace.

One thing, there is a request to add a reference to RFC 4151 into rfc6087bis if possible.  rfc6087bis is currently in AD Evaluation state, so there may still be an opportunity to do this.

Thanks,
Kent // as co-chair
