16 * Each <code>Document</code> has a <code>doctype</code> attribute whose value
17 * is either <code>null</code> or a <code>DocumentType</code> object. The
18 * <code>DocumentType</code> interface in the DOM Core provides an interface
19 * to the list of entities that are defined for the document, and little
20 * else because the effect of namespaces and the various XML schema efforts
21 * on DTD representation are not clearly understood as of this writing.
22 * <p>DOM Level 3 doesn't support editing <code>DocumentType</code> nodes.
23 * <code>DocumentType</code> nodes are read-only.
24 * <p>See also the <a href='http://www.w3.org/TR/2004/REC-DOM-Level-3-Core-20040407'>Document Object Model (DOM) Level 3 Core Specification</a>.

28 * The name of DTD; i.e., the name immediately following the

31 public String getName();
34 * A <code>NamedNodeMap</code> containing the general entities, both
35 * external and internal, declared in the DTD. Parameter entities are
36 * not contained. Duplicates are discarded. For example in:
38 * ex SYSTEM "ex.dtd" [ <!ENTITY foo "foo"> <!ENTITY bar
39 * "bar"> <!ENTITY bar "bar2"> <!ENTITY % baz "baz">
40 * ]> <ex/></pre>
41 * the interface provides access to <code>foo</code>
42 * and the first declaration of <code>bar</code> but not the second
43 * declaration of <code>bar</code> or <code>baz</code>. Every node in
44 * this map also implements the <code>Entity</code> interface.
45 * <br>The DOM Level 2 does not support editing entities, therefore
46 * <code>entities</code> cannot be altered in any way.
48 public NamedNodeMap getEntities();
51 * A <code>NamedNodeMap</code> containing the notations declared in the
52 * DTD. Duplicates are discarded. Every node in this map also implements
53 * the <code>Notation</code> interface.
54 * <br>The DOM Level 2 does not support editing notations, therefore
55 * <code>notations</code> cannot be altered in any way.

74 * This is does not contain the delimiting square brackets.

76 * information is available to the implementation. This may vary
