"Parsing custom STIX objects and/or STIX objects with custom properties is also completed easily with [parse()](../api/stix2.parsing.rst#stix2.parsing.parse). Just supply the keyword argument ``allow_custom=True``. When ``allow_custom`` is specified, [parse()](../api/stix2.parsing.rst#stix2.parsing.parse) will attempt to convert the supplied STIX content to known STIX 2 domain objects and/or previously defined [custom STIX 2 objects](custom.ipynb). If the conversion cannot be completed (and ``allow_custom`` is specified), [parse()](../api/stix2.parsing.rst#stix2.parsing.parse) will treat the supplied STIX 2 content as valid STIX 2 objects and return them. This is an axiomatic possibility as the ``stix2`` library cannot guarantee proper processing of unknown custom STIX 2 objects that were explicitly flagged to be allowed, and thus may not be valid.\n",
