    # A Resource Resolver takes a concrete object (like a model instance) and
    # resolves it into all {Resource}s for which a permit would allow an action.
    # For example, this can be used to grant a credential on all items of a given
    # model class or to implement cascading permissions when all credentials for
    # a container should apply to the contained objects.
    #
    # NOTE: This implementation currently always resolves to the entity and its
    # type and nothing more. This needs some thought on an appropriate extension
    # mechanism to mirror the {PermissionMapper}.
