Description:
 def resource_references(self, resource) -> Mapping[str, List[Any]]: """ Resolve and return reference resources pointed to by object Fields in resource.props can flag that they are references by using the references type. This method scans the model, finds any fields that are references, and returns the reference resources pointed to by those references. Note that we shouldn't get to the point of dangling references. Our custom Sphinx event should raise a references error during the build process (though maybe it is just a warning?) """
