-        Note:
-            The argument ``pretty=True`` will output the STIX object following
-            spec order. Using this argument greatly impacts object serialization
-            performance. If your use case is centered across machine-to-machine
-            operation it is recommended to set ``pretty=False``.

-            When ``pretty=True`` the following key-value pairs will be added or
