	// Sep 14, 2000:
	// Fixed serializer to report IO exception directly, instead at
	// the end of document processing.
	// Reported by Patrick Higgins <phiggins@transzap.com>
	// Aug 21, 2000:
	// Fixed bug in startDocument not calling prepare.
	// Reported by Mikael Staldal <d96-mst-ingen-reklam@d.kth.se>
	// Aug 21, 2000:
	// Added ability to omit DOCTYPE declaration.
	// Sep 1, 2000:
	// If no output format is provided the serializer now defaults
	// to ISO-8859-1 encoding. Reported by Mikael Staldal
	// <d96-mst@d.kth.se>

	/**
	* Implements an HTML/XHTML serializer supporting both DOM and SAX
	* pretty serializing. HTML/XHTML mode is determined in the
	* constructor. For usage instructions see {@link Serializer}.
	* <p>
	* If an output stream is used, the encoding is taken from the
	* output format (defaults to <tt>UTF-8</tt>). If a writer is
	* used, make sure the writer uses the same encoding (if applies)
	* as specified in the output format.
	* <p>
	* The serializer supports both DOM and SAX. DOM serializing is done
	* by calling {@link #serialize} and SAX serializing is done by firing
	* SAX events and using the serializer as a document handler.
	* <p>
	* If an I/O exception occurs while serializing, the serializer
	* will not throw an exception directly, but only throw it
	* at the end of serializing (either DOM or SAX's {@link
	* org.xml.sax.DocumentHandler#endDocument}.
	* <p>
	* For elements that are not specified as whitespace preserving,
	* the serializer will potentially break long text lines at space
	* boundaries, indent lines, and serialize elements on separate
	* lines. Line terminators will be regarded as spaces, and
	* spaces at beginning of line will be stripped.
	* <p>
	* XHTML is slightly different than HTML:
	* <ul>
	* <li>Element/attribute names are lower case and case matters
	* <li>Attributes must specify value, even if empty string
	* <li>Empty elements must have '/' in empty tag
	* <li>Contents of SCRIPT and STYLE elements serialized as CDATA
	* </ul>
	*
	* @deprecated This class was deprecated in Xerces 2.6.2. It is
	* recommended that new applications use JAXP's Transformation API
	* for XML (TrAX) for serializing HTML. See the Xerces documentation
	* for more information.
