<p>The <dfn id=term-dom-dtdef><abbr>DOM</abbr> Document Type Definition</dfn>
module is a set of <abbr>DOM</abbr> interfaces, including both new
interfaces and modifications to existing <abbr>DOM</abbr> interfaces,
over which <abbr>DOM</abbr> applications are able to access to the
definitions of the document type.</p>

<p>Interfaces defined in this specification are partially modeled from
early drafts of <abbr>DOM</abbr> level 1 <span class=ed>@@ ref</span>,
<abbr>DOM</abbr> Abstract Schema level 3 <span class=ed>@@ ref</span>, and

<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>
<ul>
<li><a href="#DocumentXDoctype"><code>DocumentXDoctype</code></a></li>
<li><a href="#DocumentTypeDefinition"><code>DocumentTypeDefinition</code></a></li>
<li><a href="#ElementTypeDefinition"><code>ElementTypeDefinition</code></a></li>
<li><a href="#AttributeDefinition"><code>AttributeDefinition</code></a></li>
</ul>

<p>In addition, it modifies interfaces
<a href="#Node"><code>Node</code></a>,
<a href="#DocumentType"><code>DocumentType</code></a>,
<a href="#Entity"><code>Entity</code></a>,
<a href="#EntityReference"><code>EntityReference</code></a>,
<a href="#Notation"><code>Notation</code></a>, and
<a href="#ProcessingInstruction"><code>ProcessingInstruction</code></a>.</p>

<div class=section id=features>
<h3>Feature Name</h3>

<p>In a <abbr>DOM</abbr> implementation that supports the version 3.0 of 
the <abbr>DOM</abbr> Document Type Definition module, the 
<code>hasFeature</code> method of a <code>DOMImplementation</code> object 
<em class=rfc2119>MUST</em> return <code>true</code> when the parameters are
set to <code>http://suika.fam.cx/www/2006/feature/XDoctype</code> and 
<code>3.0</code> respectively.</p>

<p>In such an implementation, the <code>getFeature</code> method of a 
<code>Document</code> object <em class=rfc2119>MUST</em> return the (at least
conceptually) same object implementing the
<a href="#DocumentXDoctype"><code>DocumentXDoctype</code></a> interface when
the parameters are set to 
<code>http://suika.fam.cx/www/2006/feature/XDoctype</code> and 
<code>3.0</code> respectively.  Likewise, any method that takes one or more
feature names with or without version number, including the methods
<code>hasFeature</code> and <code>getFeature</code>, 
<em class=rfc2119>MUST</em> behave in a manner consistent with the 
aforementioned cases.</p>

All entities declared in the document type definition
contained in or referenced from the document entity
might not be exposed through this collection, depending
on the information provided by the XML processor for
the DOM implementation.  In particular, it might not

expose an [CODE(DOMi)@en[[[Entity]]]] node whose [CODE(DOMa)@en[[[nodeName]]]]

;; This definition is based on one for the

Since duplication is violation to the Validity Constraint,
XML parsers might vary on how notations are notified to

is so defined that in case ''any'' notation is declared for 
multiple times then the property has no value.

<p class=ed>
 The publicId attribute and the systemId attribute of DocumentType, Entity, and Notation objects are now read-write.

The setter MUST throw a NO_MODIFICATION_ALLOWED_ERR DOMException if the Node object is read-only. Otherwise, it MUST set the specified value to the attribute. No normalization, lexical validation, or relative reference resolving is performed. null, which represents no public or system identifier is provided, might be specified.

Setting public or system identifier does never result in any lexical or logical structure of the document being changed. In particular, no external entity referenced by new identifier will be loaded.

Setting an invalid or non-normalized identifier might make the object non-serializable. Setting a non-null public identifier to a DocumentType or Entity object that does not have non-null system identifier or setting null as the system identifier of a DocumentType or Entity object that does have non-null public identifier will make that object non-serializable.

ISSUE: In HTML5, Firefox 1.5, and Opera 9, not specifying public or system identifier results in empty strings.
