+### Target
+Target of the access control rule in access control list.
+
+| Name | Number | Description |
+| ---- | ------ | ----------- |
+| Unknown | 0 | Unknown target, default value. |
+| User | 1 | User target rule is applied if sender is the owner of the container. |
+| System | 2 | System target rule is applied if sender is the storage node within the container or inner ring node. |
+| Others | 3 | Others target rule is applied if sender is not user or system target. |
+| PubKey | 4 | PubKey target rule is applied if sender has public key provided in extended ACL. |

+| <a name="uint64" /> uint64 | Uses variable-length encoding. | uint64 | long | int/long |
+| <a name="sint32" /> sint32 | Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s. | int32 | int | int |
+| <a name="sint64" /> sint64 | Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int64s. | int64 | long | int/long |
+| <a name="fixed32" /> fixed32 | Always four bytes. More efficient than uint32 if values are often greater than 2^28. | uint32 | int | int |
+| <a name="fixed64" /> fixed64 | Always eight bytes. More efficient than uint64 if values are often greater than 2^56. | uint64 | long | int/long |

+| <a name="sfixed64" /> sfixed64 | Always eight bytes. | int64 | long | int/long |
+| <a name="bool" /> bool |  | bool | boolean | boolean |
+| <a name="string" /> string | A string must always contain UTF-8 encoded or 7-bit ASCII text. | string | String | str/unicode |
+| <a name="bytes" /> bytes | May contain any arbitrary sequence of bytes. | string | ByteString | str |
