Scott,

I foresee the need for defining new JSON Values Registry Type values that are 
associated with new RDAP extensions.  It looks like 
draft-ietf-regext-rdap-redacted is the first to do this for the three new types 
"redacted name", "redacted reason", and "redacted expression language".  
Without extensibility of the JSON Values Registry Type values, the extensions 
will need to update RFC 7083, extensions will need to setup their own RDAP JSON 
Value-like registries, or extensions won't register anything at all.  I view 
the JSON Values Registry as providing a central place to normalize and help 
RDAP clients understand the meaning of the values in the RDAP responses.  There 
is no way that RFC 7083 can foresee the members and types needed by RDAP 
extensions.  The Expert Review policy in RFC 8126 is perfect to support a 
variety of use cases to register RDAP JSON response values, but the fixed 
number of Type values won't meet the need.  Can a new Type value be defined for 
a proprietary RDAP extension, which could not update RFC 7083 to add the 
registrations.  My concern is that the registrations will not be done at the 
determinate of RDAP clients.

Does the sentence in section 10.2 "JSON Values Registry" "This new registry is 
for use in the notices and remarks (Section 4.3), status (Section 4.6), role 
(Section 5.1), event action (Section 4.5), and domain variant relation (Section 
5.3) fields specified in RDAP" only allow for the registration of that static 
list of types, considering that it's not normative (e.g., This new registry 
MUST only be used in...")?  In addition, the language for the Type entry is 
"the type of value being registered. It should be one of the following:", where 
there is no normative MUST with the static list of type values.  

My recommendation is to leave the addition of registration in the JSON Values 
Registry with the inclusion of new Type values up to the Expert Review policy 
and don't go down the path of updating RFC 7083.  The experts can help assess 
the applicability of the registrations without added restriction of having to 
update RFC 7083 to do so.  The registration will include the associated RFC 
reference in them, so there should be no question where the Type and entries 
originated from.

[SAH] I'm somewhat embarrassed to admit this since both Andy and I have 
reviewed this document during its development in the regext working group, but 
I think I've found a small issue. RFC 9083 defines a set of "type" values for 
use in the RDAP JSON values registry. draft-ietf-regext-rdap-redacted defines 
three additional type values, which means it's updating RFC 9083 and the set 
of type values allowed for use in the registry. The document needs to be clear 
about the fact that it's updating 9083, which it doesn't currently do. This 
would also mean that the registry itself will need to be update to note that 
this RFC-to-be is one of the references that defines the structure of the 
registry.


Having said that, the requested addition to the registry looks fine to me.


Scott
