RFC 9200, "Authentication and Authorization for Constrained Environments Using the OAuth 2.0 Framework (ACE-OAuth)", August 2022

Errata ID: 8232
Status: Reported
Type: Technical
Publication Format(s) : HTML
Reported By: Marco Tiloca

Section 5.8.2 says:

/ ace_profile / 38 : "coap_dtls",

It should say:

/ ace_profile / 38 : 1 / coap_dtls /,

Notes:

The example in Figure 7 shows a response with Content-Format "application/ace+cbor". Therefore, the value of the parameter 'ace_profile' must be encoded as a CBOR integer, consistent with Section 5.8.4.3 that says:

> A profile MUST specify an identifier that MUST be used to uniquely identify itself in the ace_profile parameter. The textual representation of the profile identifier is intended for human readability and for JSON-based interactions; it MUST NOT be used for CBOR-based interactions.
