+class XML_API Attr: public AbstractNode
+	/// The Attr interface represents an attribute in an Element object. Typically
+	/// the allowable values for the attribute are defined in a document type definition.
+	/// 
+	/// Attr objects inherit the Node interface, but since they are not actually
+	/// child nodes of the element they describe, the DOM does not consider them
+	/// part of the document tree. Thus, the Node attributes parentNode, previousSibling,
+	/// and nextSibling have a null value for Attr objects. The DOM takes the view
+	/// that attributes are properties of elements rather than having a separate
+	/// identity from the elements they are associated with; this should make it
+	/// more efficient to implement such features as default attributes associated
+	/// with all elements of a given type. Furthermore, Attr nodes may not be immediate
+	/// children of a DocumentFragment. However, they can be associated with Element
+	/// nodes contained within a DocumentFragment. In short, users and implementors
+	/// of the DOM need to be aware that Attr nodes have some things in common with
+	/// other objects inheriting the Node interface, but they also are quite distinct.
+	/// 
+	/// The attribute's effective value is determined as follows: if this attribute
+	/// has been explicitly assigned any value, that value is the attribute's effective
+	/// value; otherwise, if there is a declaration for this attribute, and that
+	/// declaration includes a default value, then that default value is the attribute's
+	/// effective value; otherwise, the attribute does not exist on this element
+	/// in the structure model until it has been explicitly added. Note that the
+	/// nodeValue attribute on the Attr instance can also be used to retrieve the
+	/// string version of the attribute's value(s).
+	/// 
+	/// In XML, where the value of an attribute can contain entity references, the
+	/// child nodes of the Attr node provide a representation in which entity references
+	/// are not expanded. These child nodes may be either Text or EntityReference
+	/// nodes. Because the attribute type may be unknown, there are no tokenized

+		/// then the specified flag is automatically flipped to true. To re-specify
+		/// the attribute as the default value from the DTD, the user must delete the

+	/// could fulfill this role, a Document object can potentially be a heavyweight
+	/// object, depending on the underlying implementation. What is really needed
+	/// for this is a very lightweight object. DocumentFragment is such an object.
+	/// 
+	/// Furthermore, various operations -- such as inserting nodes as children of
+	/// another Node -- may take DocumentFragment objects as arguments; this results
+	/// in all the child nodes of the DocumentFragment being moved to the child
+	/// list of this node.

+	/// nodes do not need to be well-formed XML documents (although they do need

+	/// can have multiple top nodes). For example, a DocumentFragment might have
+	/// only one child and that child node could be a Text node. Such a structure
+	/// model represents neither an HTML document nor a well-formed XML document.
+	/// 
+	/// When a DocumentFragment is inserted into a Document (or indeed any other

+class XML_API XMLStreamParser
+	/// The streaming XML pull parser and streaming XML serializer. The parser
+	/// is a conforming, non-validating XML 1.0 implementation (see Implementation Notes
+	/// for details). The application character encoding (that is, the encoding used
+	/// in the application's memory) for both parser and serializer is UTF-8.
+	/// The output encoding of the serializer is UTF-8 as well. The parser supports
+	/// UTF-8, UTF-16, ISO-8859-1, and US-ASCII input encodings.
+	///
+	/// Attribute map:
+	///
+	/// Attribute map lookup. If attribute is not found, then the version
+	/// without the default value throws an appropriate parsing exception
+	/// while the version with the default value returns that value.
+	///
+	/// Note also that there is no attribute(ns, name) version since it
+	/// would conflict with attribute(name, dv) (qualified attributes
+	/// are not very common).
+	///
+	/// Attribute map is valid throughout at the "element level" until
+	/// end_element and not just during EV_START_ELEMENT. As a special case,
+	/// the map is still valid after peek() that returned end_element until
+	/// this end_element event is retrieved with next().
+	///
+	/// Using parser:
+	///
+	///     XMLStreamParser p(ifs, argv[1]);
+	///     for (XMLStreamParser::EventType e: p)
+	///     {

+	///             cerr << p.line () << ':' << p.column () << ": start " << p.name () << endl;

+class XML_API XMLWriter: public ContentHandler, public LexicalHandler, public DTDHandler
+	/// This class serializes SAX2 ContentHandler, LexicalHandler and
+	/// DTDHandler events back into a stream.
+	/// 
+	/// Various consistency checks are performed on the written data
+	/// (i.e. there must be exactly one root element and every startElement() 
+	/// must have a matching endElement()).
+	///
+	/// The XMLWriter supports optional pretty-printing of the serialized XML.
+	/// Note, however, that pretty-printing XML data alters the
+	/// information set of the document being written, since in
+	/// XML all whitespace is potentially relevant to an application.
+	///
+	/// The writer contains extensive support for XML Namespaces, so that a client  
+	/// application does not have to keep track of prefixes and supply xmlns attributes.
+	///
+	/// If the client does not provide namespace prefixes (either by specifying them
+	/// as part of the qualified name given to startElement(), or by calling
+	/// startPrefixMapping()), the XMLWriter automatically generates namespace
+	/// prefixes in the form ns1, ns2, etc.
