16 * The <code>Document</code> interface represents the entire HTML or XML
\r
17 * document. Conceptually, it is the root of the document tree, and provides
\r
18 * the primary access to the document's data.
\r
19 * <p>Since elements, text nodes, comments, processing instructions, etc.
\r
20 * cannot exist outside the context of a <code>Document</code>, the
\r
21 * <code>Document</code> interface also contains the factory methods needed
\r
22 * to create these objects. The <code>Node</code> objects created have a
\r
23 * <code>ownerDocument</code> attribute which associates them with the
\r
24 * <code>Document</code> within whose context they were created.
\r
