Summary: This draft is on the right track but has open issues, described in the review.

Major Issue:

Many of the descriptions describe only side-effects of the status instead of the status itself.

All of the descriptions for the new rdap status codes start with "For DNR that indicates". This implies that there is a "For not DNR" case that's not discussed. I don't think the phrase is necessary and each description should look more like the other descriptions already registered at http://www.iana.org/assignments/rdap-json-values/rdap-json-values.xhtml.

For instance, at 'auto renew period' the document currently says:

"For DNR that indicates if the object is deleted by the registrar during this period, the registry provides a credit to the registrar for the cost of the auto renewal"

That discusses something (and not the only thing) that can happen while the object is in that state. It does not describe the state.

I suggest it should instead say (based on the text in 3915 and the current registry entry style):

"The object instance is in a grace period provided between when its registration period expires and when its registration is automatically renewed by the registry."

I don't think it's important to include the commentary about providing a credit if the entity is deleted by the registrar during this period, but since that commentary exists in 3915, you can include it if you want. The _important_ part to convey is the actual status.

All of the descriptions will need similar attention. Some of them (such as clientUpdateProhibited) currently have 2119 words in the description. That doesn't make sense - this is a status, not an protocol instruction, and trying to put normative language in a registry will lead to confusion about where the behavior you are trying to describe is actually defined. (To be fair, 5731 has this same problem). Again, I suggest following the style that's already in the registry and say something like "The client has requested that any requests to update this object instance be rejected."


Minor Issues:

You're setting up a minor maintenance headache for any future work that might update this document by having the descriptions listed in two places. I don't think it's necessary to list the descriptions in section 2 (currently the bulk of page 4 and the beginning of page 5). Instead, stop after the paragraph that ends at the top of page 4, and note that the descriptions of each new status code are provided in section 3.

Nits:

Near the end of page 3, the document says "In the DNR, the client and server prohibited statuses are separate an RDAP MUST support the same separation." There are several nits to address with this. That MUST is not a good use of 2119. DNR hasn't been expanded (and "the DNR" is not particularly clear).

I suggest you replace that sentence, and the one immediately before it with:

"EPP provides status codes that allow distinguishing the case that an action is prohibited because of server policy from the case that an action is prohibited because of a client request. The ability to make this distinction needs to be preserved in RDAP."
