+ * An output to a P2WSH script which can be spent with a single signature after an `OP_CSV`
+ * delay.
+ *
+ * The witness in the spending input should be:
+ * ```bitcoin
+ * <BIP 143 signature> <empty vector> (MINIMALIF standard rule) <provided witnessScript>
+ * ```
+ *
+ * Note that the `nSequence` field in the spending input must be set to
+ * [`DelayedPaymentOutputDescriptor::to_self_delay`] (which means the transaction is not
+ * broadcastable until at least [`DelayedPaymentOutputDescriptor::to_self_delay`] blocks after
+ * the outpoint confirms, see [BIP
+ * 68](https://github.com/bitcoin/bips/blob/master/bip-0068.mediawiki)). Also note that LDK
+ * won't generate a [`SpendableOutputDescriptor`] until the corresponding block height
+ * is reached.
+ *
+ * These are generally the result of a \"revocable\" output to us, spendable only by us unless
+ * it is an output from an old state which we broadcast (which should never happen).
+ *
+ * To derive the delayed payment key which is used to sign this input, you must pass the
+ * holder [`InMemorySigner::delayed_payment_base_key`] (i.e., the private key which corresponds to the
+ * [`ChannelPublicKeys::delayed_payment_basepoint`] in [`ChannelSigner::pubkeys`]) and the provided
+ * [`DelayedPaymentOutputDescriptor::per_commitment_point`] to [`chan_utils::derive_private_key`]. The DelayedPaymentKey can be
+ * generated without the secret key using [`DelayedPaymentKey::from_basepoint`] and only the
+ * [`ChannelPublicKeys::delayed_payment_basepoint`] which appears in [`ChannelSigner::pubkeys`].
+ *
+ * To derive the [`DelayedPaymentOutputDescriptor::revocation_pubkey`] provided here (which is
+ * used in the witness script generation), you must pass the counterparty
+ * [`ChannelPublicKeys::revocation_basepoint`] (which appears in the call to
+ * [`ChannelSigner::provide_channel_parameters`]) and the provided
+ * [`DelayedPaymentOutputDescriptor::per_commitment_point`] to
+ * [`RevocationKey`].
+ *
+ * The witness script which is hashed and included in the output `script_pubkey` may be
+ * regenerated by passing the [`DelayedPaymentOutputDescriptor::revocation_pubkey`] (derived
+ * as explained above), our delayed payment pubkey (derived as explained above), and the
+ * [`DelayedPaymentOutputDescriptor::to_self_delay`] contained here to
+ * [`chan_utils::get_revokeable_redeemscript`].
