/**
* Interface for a DOM serializer implementation, factory for DOM and SAX
* serializers, and static methods for serializing DOM documents.
*
* To serialize a document using SAX events, create a compatible serializer
* and pass it around as a {@link
* org.xml.sax.DocumentHandler}. If an I/O error occurs while serializing, it will
* be thrown by {@link DocumentHandler#endDocument}. The SAX serializer
* may also be used as {@link org.xml.sax.DTDHandler}, {@link org.xml.sax.ext.DeclHandler} and
* {@link org.xml.sax.ext.LexicalHandler}.
*
* To serialize a DOM document or DOM element, create a compatible
* serializer and call it's {@link
* DOMSerializer#serialize(Document)} or {@link DOMSerializer#serialize(Element)} methods.
* Both methods would produce a full XML document, to serizlie only
* the portion of the document use {@link OutputFormat#setOmitXMLDeclaration}
* and specify no document type.
*
* The {@link OutputFormat} dictates what underlying serialized is used
* to serialize the document based on the specified method. If the output
* format or method are missing, the default is an XML serializer with
* UTF-8 encoding and now indentation.
