732    <pre class=ed>
733    [7] The
734    [DFN@en[definition group [CODE(DOM)@en[[[DefaultValueType]]]]]]
735    contains integers indicating the type of
736    default attribute value:
737    ,[CODE(DOMc)@en[[[UNKNOWN_DEFAULT]]]],[CODE(IDL)[[[0]]]],The default value is unknown.
738    ,[CODE(DOMc)@en[[[FIXED_DEFAULT]]]],[CODE(IDL)[[[1]]]],The default value is provided and the attribute is [CODE(XML)@en[#[[FIXED]]]] to that value.
739    ,[CODE(DOMc)@en[[[REQUIRED_DEFAULT]]]],[CODE(IDL)[[[2]]]],An attribute specification is [CODE(XML)@en[#[[REQUIRED]]]] for the attribute.
740    ,[CODE(DOMc)@en[[[IMPLIED_DEFAULT]]]],[CODE(IDL)[[[3]]]],The default value is [CODE(XML)@en[#[[IMPLIED]]]].
741    ,[CODE(DOMc)@en[[[EXPLICIT_DEFAULT]]]],[CODE(IDL)[[[4]]]],The default value is provided but the attribute is not fixed to it.
742    
743    The type of these constants are
744    [CODE(IDL)@en[[[unsigned]] [[short]]]].
745    
746    If the source of the attribute default value type
747    does not distinguish the [CODE(XML)@en[#[[IMPLIED]]]]
748    default and unknown default, then the
749    [CODE(DOMc)@en[[[IMPLIED_DEFAULT]]]] value
750    [['''MUST''']] be used.
751    
752    ;; A newly created [CODE(DOMi)@en[[[AttributeDefinition]]]]
753    object by [CODE(DOMm)@en[[[createAttributeDefinition]]]]
754    method has [CODE(DOMa)@en[[[declaredType]]]] attribute
755    set to [CODE(DOMc)@en[[[NO_TYPE_ATTR]]]].
