  <h2><abbr>DOM</abbr> Document Type Definition Module</h2>
  <p>The <abbr>DOM</abbr> Document Type Definition module, version 3.0,
- consists of three interfaces:</p>
+ introduces four interfaces:
- <ul>
+ <a href="#DocumentXDoctype"><code>DocumentXDoctype</code></a>,
- <li><a href="#DocumentXDoctype"><code>DocumentXDoctype</code></a></li>
+ <a href="#DocumentTypeDefinition"><code>DocumentTypeDefinition</code></a>,
- <li><a href="#DocumentTypeDefinition"><code>DocumentTypeDefinition</code></a></li>
+ <a href="#ElementTypeDefinition"><code>ElementTypeDefinition</code></a>,
- <li><a href="#ElementTypeDefinition"><code>ElementTypeDefinition</code></a></li>
+ and <a href="#AttributeDefinition"><code>AttributeDefinition</code></a>.
- <li><a href="#AttributeDefinition"><code>AttributeDefinition</code></a></li>
+ In addition, it modifies existing interfaces
- </ul>
- <p>In addition, it adds methods, attributes, and/or constants to interfaces
  <a href="#Node"><code>Node</code></a>,
- <a href="#Entity"><code>Entity</code></a>,
+ <a href="#Document"><code>Document</code></a>,
- <a href="#EntityReference"><code>EntityReference</code></a>, and

- <a href="#Node"><code>Node</code></a> and
