+/**
+ *  A <code>LSSerializer</code> provides an API for serializing (writing) a
+ * DOM document out into XML. The XML data is written to a string or an
+ * output stream. Any changes or fixups made during the serialization affect
+ * only the serialized data. The <code>Document</code> object and its
+ * children are never altered by the serialization operation.
+ * <p> During serialization of XML data, namespace fixup is done as defined in [<a href='http://www.w3.org/TR/2004/REC-DOM-Level-3-Core-20040407'>DOM Level 3 Core</a>]
+ * , Appendix B. [<a href='http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113'>DOM Level 2 Core</a>]
+ *  allows empty strings as a real namespace URI. If the
+ * <code>namespaceURI</code> of a <code>Node</code> is empty string, the
+ * serialization will treat them as <code>null</code>, ignoring the prefix
+ * if any.
+ * <p> <code>LSSerializer</code> accepts any node type for serialization. For
+ * nodes of type <code>Document</code> or <code>Entity</code>, well-formed
+ * XML will be created when possible (well-formedness is guaranteed if the
+ * document or entity comes from a parse operation and is unchanged since it
+ * was created). The serialized output for these node types is either as a
+ * XML document or an External XML Entity, respectively, and is acceptable
+ * input for an XML parser. For all other types of nodes the serialized form
+ * is implementation dependent.
+ * <p>Within a <code>Document</code>, <code>DocumentFragment</code>, or
+ * <code>Entity</code> being serialized, <code>Nodes</code> are processed as
+ * follows
+ * <ul>
+ * <li> <code>Document</code> nodes are written, including the XML
+ * declaration (unless the parameter "xml-declaration" is set to
+ * <code>false</code>) and a DTD subset, if one exists in the DOM. Writing a
+ * <code>Document</code> node serializes the entire document.
+ * </li>
+ * <li>
+ * <code>Entity</code> nodes, when written directly by
+ * <code>LSSerializer.write</code>, outputs the entity expansion but no
+ * namespace fixup is done. The resulting output will be valid as an
+ * external entity.
+ * </li>
+ * <li> If the parameter "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-entities'>
+ * entities</a>" is set to <code>true</code>, <code>EntityReference</code> nodes are
+ * serialized as an entity reference of the form "
+ * <code>&amp;entityName;</code>" in the output. Child nodes (the expansion)
+ * of the entity reference are ignored. If the parameter "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-entities'>
+ * entities</a>" is set to <code>false</code>, only the children of the entity reference
+ * are serialized. <code>EntityReference</code> nodes with no children (no
+ * corresponding <code>Entity</code> node or the corresponding
+ * <code>Entity</code> nodes have no children) are always serialized.
+ * </li>
+ * <li>
+ * <code>CDATAsections</code> containing content characters that cannot be
+ * represented in the specified output encoding are handled according to the
+ * "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-split-cdata-sections'>
+ * split-cdata-sections</a>" parameter.  If the parameter is set to <code>true</code>,
+ * <code>CDATAsections</code> are split, and the unrepresentable characters
+ * are serialized as numeric character references in ordinary content. The
+ * exact position and number of splits is not specified.  If the parameter
+ * is set to <code>false</code>, unrepresentable characters in a
+ * <code>CDATAsection</code> are reported as
+ * <code>"wf-invalid-character"</code> errors if the parameter "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-well-formed'>
+ * well-formed</a>" is set to <code>true</code>. The error is not recoverable - there is no
+ * mechanism for supplying alternative characters and continuing with the
+ * serialization.
+ * </li>
+ * <li> <code>DocumentFragment</code> nodes are serialized by
+ * serializing the children of the document fragment in the order they
+ * appear in the document fragment.
+ * </li>
+ * <li> All other node types (Element, Text,
+ * etc.) are serialized to their corresponding XML source form.
+ * </li>
+ * </ul>
+ * <p ><b>Note:</b>  The serialization of a <code>Node</code> does not always
+ * generate a well-formed XML document, i.e. a <code>LSParser</code> might
+ * throw fatal errors when parsing the resulting serialization.
+ * <p> Within the character data of a document (outside of markup), any
+ * characters that cannot be represented directly are replaced with
+ * character references. Occurrences of '&lt;' and '&amp;' are replaced by
+ * the predefined entities &amp;lt; and &amp;amp;. The other predefined
+ * entities (&amp;gt;, &amp;apos;, and &amp;quot;) might not be used, except
+ * where needed (e.g. using &amp;gt; in cases such as ']]&gt;'). Any
+ * characters that cannot be represented directly in the output character
+ * encoding are serialized as numeric character references (and since
+ * character encoding standards commonly use hexadecimal representations of
+ * characters, using the hexadecimal representation when serializing
+ * character references is encouraged).
+ * <p> To allow attribute values to contain both single and double quotes, the
+ * apostrophe or single-quote character (') may be represented as
+ * "&amp;apos;", and the double-quote character (")  as "&amp;quot;". New
+ * line characters and other characters that cannot be represented directly
+ * in attribute values in the output character encoding are serialized as a
+ * numeric character reference.
+ * <p> Within markup, but outside of attributes, any occurrence of a character
+ * that cannot be represented in the output character encoding is reported
+ * as a <code>DOMError</code> fatal error. An example would be serializing
+ * the element &lt;LaCa\u00f1ada/&gt; with <code>encoding="us-ascii"</code>.
+ * This will result with a generation of a <code>DOMError</code>
+ * "wf-invalid-character-in-node-name" (as proposed in "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-well-formed'>
+ * well-formed</a>").
+ * <p> When requested by setting the parameter "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-normalize-characters'>
+ * normalize-characters</a>" on <code>LSSerializer</code> to true, character normalization is
+ * performed according to the definition of <a href='http://www.w3.org/TR/2004/REC-xml11-20040204/#dt-fullnorm'>fully
+ * normalized</a> characters included in appendix E of [<a href='http://www.w3.org/TR/2004/REC-xml11-20040204/'>XML 1.1</a>] on all
+ * data to be serialized, both markup and character data. The character
+ * normalization process affects only the data as it is being written; it
+ * does not alter the DOM's view of the document after serialization has
+ * completed.
+ * <p> Implementations are required to support the encodings "UTF-8",
+ * "UTF-16", "UTF-16BE", and "UTF-16LE" to guarantee that data is
+ * serializable in all encodings that are required to be supported by all
+ * XML parsers. When the encoding is UTF-8, whether or not a byte order mark
+ * is serialized, or if the output is big-endian or little-endian, is
+ * implementation dependent. When the encoding is UTF-16, whether or not the
+ * output is big-endian or little-endian is implementation dependent, but a
+ * Byte Order Mark must be generated for non-character outputs, such as
+ * <code>LSOutput.byteStream</code> or <code>LSOutput.systemId</code>. If
+ * the Byte Order Mark is not generated, a "byte-order-mark-needed" warning
+ * is reported. When the encoding is UTF-16LE or UTF-16BE, the output is
+ * big-endian (UTF-16BE) or little-endian (UTF-16LE) and the Byte Order Mark
+ * is not be generated. In all cases, the encoding declaration, if
+ * generated, will correspond to the encoding used during the serialization
+ * (e.g. <code>encoding="UTF-16"</code> will appear if UTF-16 was
+ * requested).
+ * <p> Namespaces are fixed up during serialization, the serialization process
+ * will verify that namespace declarations, namespace prefixes and the
+ * namespace URI associated with elements and attributes are consistent. If
+ * inconsistencies are found, the serialized form of the document will be
+ * altered to remove them. The method used for doing the namespace fixup
+ * while serializing a document is the algorithm defined in Appendix B.1,
+ * "Namespace normalization", of [<a href='http://www.w3.org/TR/2004/REC-DOM-Level-3-Core-20040407'>DOM Level 3 Core</a>]
+ * .
+ * <p> While serializing a document, the parameter "discard-default-content"
+ * controls whether or not non-specified data is serialized.
+ * <p> While serializing, errors and warnings are reported to the application
+ * through the error handler (<code>LSSerializer.domConfig</code>'s "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-error-handler'>
+ * error-handler</a>" parameter). This specification does in no way try to define all possible
+ * errors and warnings that can occur while serializing a DOM node, but some
+ * common error and warning cases are defined. The types (
+ * <code>DOMError.type</code>) of errors and warnings defined by this
+ * specification are:
+ * <dl>
+ * <dt><code>"no-output-specified" [fatal]</code></dt>
+ * <dd> Raised when
+ * writing to a <code>LSOutput</code> if no output is specified in the
+ * <code>LSOutput</code>. </dd>
+ * <dt>
+ * <code>"unbound-prefix-in-entity-reference" [fatal]</code> </dt>
+ * <dd> Raised if the
+ * configuration parameter "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-namespaces'>
+ * namespaces</a>" is set to <code>true</code> and an entity whose replacement text
+ * contains unbound namespace prefixes is referenced in a location where
+ * there are no bindings for the namespace prefixes. </dd>
+ * <dt>
+ * <code>"unsupported-encoding" [fatal]</code></dt>
+ * <dd> Raised if an unsupported
+ * encoding is encountered. </dd>
+ * </dl>
+ * <p> In addition to raising the defined errors and warnings, implementations
+ * are expected to raise implementation specific errors and warnings for any
+ * other error and warning cases such as IO errors (file not found,
+ * permission denied,...) and so on.
+ * <p>See also the <a href='http://www.w3.org/TR/2004/REC-DOM-Level-3-LS-20040407'>Document Object Model (DOM) Level 3 Load
+and Save Specification</a>.
