/**
 * The <code>DOMDocument</code> interface represents the entire XML
 * document. Conceptually, it is the root of the document tree, and provides
 * the primary access to the document's data.
 * <p>Since elements, text nodes, comments, processing instructions, etc.
 * cannot exist outside the context of a <code>DOMDocument</code>, the
 * <code>DOMDocument</code> interface also contains the factory methods needed
 * to create these objects. The <code>DOMNode</code> objects created have a
 * <code>ownerDocument</code> attribute which associates them with the
 * <code>DOMDocument</code> within whose context they were created.
 * <p>See also the <a href='http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113'>Document Object Model (DOM) Level 2 Core Specification</a>.
