147    <a href="#ElementTypeDefinition"><code>ElementTypeDefinition</code></a>,
148    and <a href="#AttributeDefinition"><code>AttributeDefinition</code></a>.
149    In addition, it modifies existing interfaces
150    <a href="#Node"><code>Node</code></a>,
151    <a href="#Document"><code>Document</code></a>,
152    <a href="#DocumentType"><code>DocumentType</code></a>,

159    <p>In a <abbr>DOM</abbr> implementation that supports the version 3.0 of
160    the <abbr>DOM</abbr> Document Type Definition module, the
161    <code>hasFeature</code> method of a <code>DOMImplementation</code> object
162    <em class=rfc2119>MUST</em> return <code>true</code> when the parameters are
163    set to
164    <dfn id=feature-XDoctype><code>http://suika.fam.cx/www/2006/feature/XDoctype</code></dfn>
165    and <dfn id=feature-XDoctype-3.0><code>3.0</code></dfn> respectively.</p>
166    
167    <p>In such an implementation, the <code>getFeature</code> method of a
168    <code>Document</code> object <em class=rfc2119>MUST</em> return the (at least
169    conceptually) same object implementing the
170    <a href="#DocumentXDoctype"><code>DocumentXDoctype</code></a> interface when
171    the parameters are set to
172    <a href="#feature-XDoctype"><code>http://suika.fam.cx/www/2006/feature/XDoctype</code></a>
173    and <a href="#feature-XDoctype-3.0"><code>3.0</code></a> respectively.  
174    Likewise, any method that takes one or more feature names with or without
175    version number, including the methods <code>hasFeature</code> and
176    <code>getFeature</code>, <em class=rfc2119>MUST</em> behave in a manner
177    consistent with the aforementioned cases.</p>

191    </pre>
192    
193    <p>This specification adds two new types (subinterfaces) of

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