+#   extension_compute_limit = <gas>
+#
+#       The extension compute limit is the maximum amount of gas that can be

+#       If this parameter is unspecified, xrpld will use an internal

+#
+#   extension_size_limit = <bytes>
+#
+#       The extension size limit is the maximum size of a WASM extension in
