Section 5.8.5 says:

+-------------------+----------+-------------+---------------+
| ace_profile       | 38       | integer     | RFC 9200      |
+-------------------+----------+-------------+---------------+

It should say:

+-------------------+----------+-------------+---------------+
| ace_profile       | 38       | Null or     | RFC 9200      |
|                   |          | integer     |               |
+-------------------+----------+-------------+---------------+

Notes:

As defined in Section 5.8.1, the parameter "ace_profile" can be included with CBOR Simple Value `null` (0xf6) in Access Token Requests. Therefore, the entry for the parameter "ace_profile" in Table 5 should not say "integer" as Value Type, but instead "Null or integer".

The entry for "ace_profile" in the IANA registry at [1] should be updated accordingly.
