class AttributeRuleSet(object):
    """
    A set of flags and indicators defining how an attribute may be used.

    Every attribute defined by the KMIP specification comes with a set of
    rules defining how and under what conditions the attribute should be
    used. This class acts as a basic struct storing those rules.

    Attributes:
        always_has_value: A flag defining if the attribute is always set.
        initially_set_by: A list of entities that can implicitly set the
            attribute.
        modifiable_by_server: A flag defining if the server can modify the
            attribute.
        modifiable_by_client: A flag defining if the client can modify the
            attribute.
        deletable_by_client: A flag defining if the client can delete the
            attribute.
        multiple_instances_permitted: A flag defining if the attribute is
            multivalued.
        implicitly_set_by: A list of operations that can implicitly set the
            attribute.
        applies_to_object_types: A list of object types that the attribute
            is applicable for.
        version_added: The KMIP version in which support for the attribute
            was added.
        version_deprecated: The KMIP version in which support for the
            attribute was deprecated.
