"Finally, custom extensions to existing Cyber Observable types can also be created. Just use the @[CustomExtension](../api/stix2.v20.observables.rst#stix2.v20.observables.CustomExtension) decorator. Note that you must provide the Cyber Observable class to which the extension applies. Again, any extra validation of the properties can be implemented by providing an ``__init__()`` but it is not required. Let's say we want to make an extension to the ``File`` Cyber Observable Object:"
