-/// Reference: https://datatracker.ietf.org/doc/html/rfc6962#section-4.1
-/// ```txt
-/// POST https://<log server>/ct/v1/add-chain
-///
-/// Inputs:
-///
-///    chain:  An array of base64-encoded certificates.  The first
-///       element is the end-entity certificate; the second chains to the
-///       first and so on to the last, which is either the root
-///       certificate or a certificate that chains to a known root
-///       certificate.
-///
-/// Outputs:
-///
-///    sct_version:  The version of the SignedCertificateTimestamp
-///       structure, in decimal.  A compliant v1 implementation MUST NOT
-///       expect this to be 0 (i.e., v1).
-///
-///    id:  The log ID, base64 encoded.  Since log clients who request an
-///       SCT for inclusion in TLS handshakes are not required to verify
-///       it, we do not assume they know the ID of the log.
-///
-///    timestamp:  The SCT timestamp, in decimal.
-///
-///    extensions:  An opaque type for future expansion.  It is likely
-///       that not all participants will need to understand data in this
-///       field.  Logs should set this to the empty string.  Clients
-///       should decode the base64-encoded data and include it in the
-///       SCT.
-///
-///    signature:  The SCT signature, base64 encoded.
-///
-/// If the "sct_version" is not v1, then a v1 client may be unable to
-/// verify the signature.  It MUST NOT construe this as an error.  (Note:
-/// Log clients don't need to be able to verify this structure; only TLS
-/// clients do.  If we were to serve the structure as a binary blob, then
-/// we could completely change it without requiring an upgrade to v1
-/// clients.)
