There is a registry for RDN attributes. It was created ny RFC 9925, and the ASN.1 module in RFC 9925 can be used as a template for the assignment of the naming attribute defined here.
https://www.iana.org/assignments/smi-numbers/smi-numbers.xhtml#smi-numbers-1.3.6.1.5.5.7.25 Can we change id-at-c509Name to id-rdna-c509Name and assign it in this registry?
