+### Revoking Authorization
+
+The admin can only revoke authorization from an `Address`, if the issuer of the
+asset has `AUTH_REVOCABLE_FLAG` set. The deauthorization will fail if the issuer
+is missing. This requirement is true for both the trustline balances of
+`Address::Account` and contract balances of `Address:Contract`. Note that when a
+trustline is deauthorized from Soroban, `AUTHORIZED_FLAG` is cleared and
+`AUTHORIZED_TO_MAINTAIN_LIABILITIES_FLAG` is set to avoid having to pull offers
+and redeeming pool shares.
