 /**
  * Filter to write an XML document from a SAX event stream.
  *
  * <p>This class can be used by itself or as part of a SAX event
  * stream: it takes as input a series of SAX2 ContentHandler
  * events and uses the information in those events to write
  * an XML document.  Since this class is a filter, it can also
  * pass the events on down a filter chain for further processing
  * (you can use the XMLWriter to take a snapshot of the current
  * state at any point in a filter chain), and it can be
  * used directly as a ContentHandler for a SAX2 XMLReader.</p>
  *
  * <p>The client creates a document by invoking the methods for
  * standard SAX2 events, always beginning with the
  * {@link #startDocument startDocument} method and ending with
  * the {@link #endDocument endDocument} method.  There are convenience
  * methods provided so that clients to not have to create empty
  * attribute lists or provide empty strings as parameters; for
  * example, the method invocation</p>
  *
  * <pre>
  * w.startElement("foo");
  * </pre>
  *
  * <p>is equivalent to the regular SAX2 ContentHandler method</p>
  *
  * <pre>
  * w.startElement("", "foo", "", new AttributesImpl());
  * </pre>
  *
  * <p>Except that it is more efficient because it does not allocate
  * a new empty attribute list each time.  The following code will send
  * a simple XML document to standard output:</p>
  *
  * <pre>
  * XMLWriter w = new XMLWriter();
  *
  * w.startDocument();
  * w.startElement("greeting");
  * w.characters("Hello, world!");
  * w.endElement("greeting");
  * w.endDocument();
  * </pre>
  *
  * <p>The resulting document will look like this:</p>
  *
  * <pre>
  * &lt;?xml version="1.0" standalone="yes"?>
  *
  * &lt;greeting>Hello, world!&lt;/greeting>
  * </pre>
  *
  * <p>In fact, there is an even simpler convenience method,
  * <var>dataElement</var>, designed for writing elements that
  * contain only character data, so the code to generate the
  * document could be shortened to</p>
  *
  * <pre>
  * XMLWriter w = new XMLWriter();
  *
  * w.startDocument();
  * w.dataElement("greeting", "Hello, world!");
  * w.endDocument();
  * </pre>
  *
  * <h2>Whitespace</h2>
  *
  * <p>According to the XML Recommendation, <em>all</em> whitespace
  * in an XML document is potentially significant to an application,
  * so this class never adds newlines or indentation.  If you
  * insert three elements in a row, as in</p>
  *
  * <pre>
  * w.dataElement("item", "1");
  * w.dataElement("item", "2");
  * w.dataElement("item", "3");
  * </pre>
  *
  * <p>you will end up with</p>
  *
  * <pre>
  * &lt;item>1&lt;/item>&lt;item>3&lt;/item>&lt;item>3&lt;/item>
  * </pre>
  *
  * <p>You need to invoke one of the <var>characters</var> methods
  * explicitly to add newlines or indentation.  Alternatively, you
  * can use {@link DataWriter}, which
  * is derived from this class -- it is optimized for writing
  * purely data-oriented (or field-oriented) XML, and does automatic
  * linebreaks and indentation (but does not support mixed content
  * properly).</p>
  *
  *
  * <h2>Namespace Support</h2>
  *
  * <p>The writer contains extensive support for XML Namespaces, so that
  * a client application does not have to keep track of prefixes and
  * supply <var>xmlns</var> attributes.  By default, the XML writer will
  * generate Namespace declarations in the form _NS1, _NS2, etc., wherever
  * they are needed, as in the following example:</p>
  *
  * <pre>
  * w.startDocument();
  * w.emptyElement("http://www.foo.com/ns/", "foo");
  * w.endDocument();
  * </pre>
  *
  * <p>The resulting document will look like this:</p>
  *
  * <pre>
  * &lt;?xml version="1.0" standalone="yes"?>
  *
  * &lt;_NS1:foo xmlns:_NS1="http://www.foo.com/ns/"/>
  * </pre>
  *
  * <p>In many cases, document authors will prefer to choose their
  * own prefixes rather than using the (ugly) default names.  The
  * XML writer allows two methods for selecting prefixes:</p>
  *
  * <ol>
  * <li>the qualified name</li>
  * <li>the {@link #setPrefix setPrefix} method.</li>
  * </ol>
  *
  * <p>Whenever the XML writer finds a new Namespace URI, it checks
  * to see if a qualified (prefixed) name is also available; if so
  * it attempts to use the name's prefix (as long as the prefix is
  * not already in use for another Namespace URI).</p>
  *
  * <p>Before writing a document, the client can also pre-map a prefix
  * to a Namespace URI with the setPrefix method:</p>
  *
  * <pre>
  * w.setPrefix("http://www.foo.com/ns/", "foo");
  * w.startDocument();
  * w.emptyElement("http://www.foo.com/ns/", "foo");
  * w.endDocument();
  * </pre>
  *
  * <p>The resulting document will look like this:</p>
  *
  * <pre>
  * &lt;?xml version="1.0" standalone="yes"?>
  *
  * &lt;foo:foo xmlns:foo="http://www.foo.com/ns/"/>
  * </pre>
  *
  * <p>The default Namespace simply uses an empty string as the prefix:</p>
  *
  * <pre>
  * w.setPrefix("http://www.foo.com/ns/", "");
  * w.startDocument();
  * w.emptyElement("http://www.foo.com/ns/", "foo");
  * w.endDocument();
  * </pre>
  *
  * <p>The resulting document will look like this:</p>
  *
  * <pre>
  * &lt;?xml version="1.0" standalone="yes"?>
  *
  * &lt;foo xmlns="http://www.foo.com/ns/"/>
  * </pre>
  *
  * <p>By default, the XML writer will not declare a Namespace until
  * it is actually used.  Sometimes, this approach will create
  * a large number of Namespace declarations, as in the following
  * example:</p>
  *
  * <pre>
  * &lt;xml version="1.0" standalone="yes"?>
  *
  * &lt;rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#">
  *  &lt;rdf:Description about="http://www.foo.com/ids/books/12345">
  *   &lt;dc:title xmlns:dc="http://www.purl.org/dc/">A Dark Night&lt;/dc:title>
  *   &lt;dc:creator xmlns:dc="http://www.purl.org/dc/">Jane Smith&lt;/dc:title>
  *   &lt;dc:date xmlns:dc="http://www.purl.org/dc/">2000-09-09&lt;/dc:title>
  *  &lt;/rdf:Description>
  * &lt;/rdf:RDF>
  * </pre>
  *
  * <p>The "rdf" prefix is declared only once, because the RDF Namespace
  * is used by the root element and can be inherited by all of its
  * descendants; the "dc" prefix, on the other hand, is declared three
  * times, because no higher element uses the Namespace.  To solve this
  * problem, you can instruct the XML writer to predeclare Namespaces
  * on the root element even if they are not used there:</p>
  *
  * <pre>
  * w.forceNSDecl("http://www.purl.org/dc/");
  * </pre>
  *
  * <p>Now, the "dc" prefix will be declared on the root element even
  * though it's not needed there, and can be inherited by its
  * descendants:</p>
  *
  * <pre>
  * &lt;xml version="1.0" standalone="yes"?>
  *
  * &lt;rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
  *             xmlns:dc="http://www.purl.org/dc/">
  *  &lt;rdf:Description about="http://www.foo.com/ids/books/12345">
  *   &lt;dc:title>A Dark Night&lt;/dc:title>
  *   &lt;dc:creator>Jane Smith&lt;/dc:title>
  *   &lt;dc:date>2000-09-09&lt;/dc:title>
  *  &lt;/rdf:Description>
  * &lt;/rdf:RDF>
  * </pre>
  *
  * <p>This approach is also useful for declaring Namespace prefixes
  * that be used by qualified names appearing in attribute values or
  * character data.</p>
