"Cyber Observable Objects have properties that can reference other Cyber Observable Objects. In order to create those references, use the ``_valid_refs`` property as shown in the following examples. It should be noted that ``_valid_refs`` is necessary when creating references to Cyber Observable Objects since some embedded references can only point to certain types, and ``_valid_refs`` helps ensure consistency. \n",

"In the following example, the IPv4Address object has its ``resolves_to_refs`` property specified. As per the spec, this property's value must be a list of reference(s) to MACAddress objects. In this case, those references are strings that state the type of the Cyber Observable Object being referenced, and are provided in ``_valid_refs``."
