Section 12.4. says:

| 0x19       | RETIRE_CONNECTION_ID | Section 19.16 | __01 |      |

It should say:

| 0x19       | RETIRE_CONNECTION_ID | Section 19.16 | ___1 |      |

Notes:

Based on the context and section 12.5 ending says:

Note that it is not possible to send the following frames in 0-RTT
packets for various reasons: ACK, CRYPTO, HANDSHAKE_DONE, NEW_TOKEN,
PATH_RESPONSE, and RETIRE_CONNECTION_ID. A server MAY treat receipt
of these frames in 0-RTT packets as a connection error of type
PROTOCOL_VIOLATION.

So, I think the RETIRE_CONNECTION_ID frame should not appear in the 0-RTT packet, only contained in the 1-RTT package.
