Re: Structured type of Client-Cert and Client-Cert-Chain

Thanks for bringing this up, Brian! And let's not forget the two from 9530, which I think are both dictionaries.

It’s in my inbox now - that’ll do.

Thanks Mark,

Does this constitute asking? Or is a more formal or polite ask needed?

Just ask your friendly local registry expert (eg me).

Hi folks of HTTP and IANA,

Are there (hopefully not heavyweight) procedures or processes available to add values for the newish "Structured Type" column in the HTTP Field Name Registry for fields, like those from RFC 9440 and 9421, which were defined as structured types per RFC 8941 before the "Structured Type" column was available on the registry?

HI Brian,

Thank you for explaining the field name registry. I wasn't aware of RFC 9651 at all!

And of course, I don’t mind if you forward my message. In addition to Client-Cert and Client-Cert-Chain, the structured data types for the Signature field and the Signature-Input field (from RFC 9421) have been explicitly defined as Dictionary. It would be great if this information could also be registered.

Hi Taka,

I think that column was only recently added to the Field Name registry by the draft that only very very recently became RFC 9651. I'd think/hope it wouldn't be an issue to update the registry entries from RFC 9440 too. Do you mind if I forward your message to some IANA and/or HTTP people to ask about getting things updated?

Hi Brian,

How are you?

The RFC 9440 Client-Cert HTTP Header Field<https://www.rfc-editor.org/rfc/rfc9440.html>, which you authored, defines the Client-Cert and Client-Cert-Chain fields. The specification explicitly states that their structured data types are Item (Byte Sequence) and List, respectively. However, this information is not reflected in the IANA Hypertext Transfer Protocol (HTTP) Field Name Registry<https://www.iana.org/assignments/http-fields/http-fields.xhtml>. It would be great if you could use your influence to have IANA update the information.

The reason for this request is that such information is useful for developers considering support for the sf flag, which is defined in Section 2.1. HTTP Fields<https://www.rfc-editor.org/rfc/rfc9421.html#section-2.1> of RFC 9421 HTTP Message Signatures<https://www.rfc-editor.org/rfc/rfc9421.html>, based on the official source.

Thank you in advance!
