Re: [webauthn] Must assertions with attestation include attested credential data? (#1792)

...ah, I see now that this is made unambiguous further down, in the [RP assertion verification procedure](https://pr-preview.s3.amazonaws.com/w3c/webauthn/pull/1663.html#sctn-verifying-assertion):

>22. 1. Verify that the AT bit in the [flags](https://pr-preview.s3.amazonaws.com/w3c/webauthn/pull/1663.html#flags) field of authData is set, indicating that [attested credential data](https://pr-preview.s3.amazonaws.com/w3c/webauthn/pull/1663.html#attested-credential-data) is included.

Still, I think it should be explicit in the authenticator operations as well. And now we have this issue as documentation of what exactly goes wrong if authenticators implement this incorrectly.
