180    <p>The implementation of the
181    <a href="#Node"><code>Node</code></a> interface
182    <em class=rfc2119>MUST</em> be modified as following:</p>

190    <p>This specification adds two new types (subinterfaces) of

198    <a href="#AttributeDefinition"><code>AttributeDefinition</code></a>).  For
199    these kinds of nodes, methods and attributes in the

 The [DFN@en[[CODE(DOMa)@en[[[defaultType]]]] attribute]]  
 of an [CODE(DOMi)@en[[[AttributeDefinition]]]] object  
 represents the type of the attribute default value.  
   
 This attribute is read-write.  
 The type of the attribute is  
 [CODE(IDL)@en[[[unsigned]] [[short]]]].  It is expected  
 that this attribute has a value from the definition group  
 [CODE(DOM)@en[[[DefaultValueType]]]].  
   
 The getter [['''MUST''']] return a value associated  
 to this attribute.  
   
 The setter [['''MUST''']]  
 throw a [CODE(DOMc)@en[[[NO_MODIFICATION_ALLOWED_ERR]]]]  
 [CODE(DOMi)@en[[[DOMException]]]] if the  
 [CODE(DOMi)@en[[[AttributeDefinition]]]] object is read-only.  
 Otherwise, the setter [['''MUST''']] set the specified  
 value as the value associated to this attribute.
