+  which can not be deleted at this time.
+
+  If a node dies and has direct children which can not be deleted,
+  then remove the pointer to the parent.
+
+  createElement and friends create double reference counts.

+/* ##### new TODOs:
+
+  Remove emtpy emthods in the *Private classes
+
+  Make a lot of the (mostly empty) methods in the public classes inline.
+  Specially constructors assignment operators and comparison operators are candidates.
+
+  The virtual isXxx functions in *Private can probably be replaced by inline methods checking the nodeType().

+  Reference counting:
+
+  Some simple rules:

+  2) If an extern object is created and gets a pointer to some intern
+     object, then the extern object increases the intern objects reference count.
+  3) If an extern object is deleted, then it decreases the reference count
+     on its associated intern object and deletes it if nobody else hold references

+       This is a cache optimization, that might in some cases be effective. The
+       dilemma is that QDomNode::childNodes() returns a list, but the
+       implementation stores the children in a linked list. Hence, in order to
+       get the children out through childNodes(), a list must be populated each
+       time, which is O(N).
+
+       DOM has the requirement of node references being live, see DOM Core
+       Level 3, 1.1.1 The DOM Structure Model, which means that changes to the
+       underlying documents must be reflected in node lists.
+
+       This mechanism, nodeListTime, is a caching optimization that reduces the
+       amount of times the node list is rebuilt, by only doing so when the
+       document actually changes. However, a change to anywhere in any document
+       invalidate all lists, since no dependency tracking is done.
+
+       It functions by that all modifying functions(insertBefore() and so on)
+       increment the count; each QDomNodeListPrivate copies nodeListTime on
+       construction, and compares its own value to nodeListTime in order to
+       determine whether it needs to rebuild.
+
+       This is reentrant. The nodeListTime may overflow, but that's ok since we
+       check for equalness, not whether nodeListTime is smaller than the list's
+       stored timestamp.

+    \class QDomImplementation
+    \reentrant
+    \brief The QDomImplementation class provides information about the
+    features of the DOM implementation.
+
+    \inmodule QtXml
+    \ingroup xml-tools
+
+    This class describes the features that are supported by the DOM
+    implementation. Currently the XML subset of DOM Level 1 and DOM
+    Level 2 Core are supported.
+
+    Normally you will use the function QDomDocument::implementation()
+    to get the implementation object.
+
+    You can create a new document type with createDocumentType() and a
+    new document with createDocument().
+
+    For further information about the Document Object Model see
+    \l{http://www.w3.org/TR/REC-DOM-Level-1/}{Level 1} and
+    \l{http://www.w3.org/TR/DOM-Level-2-Core/}{Level 2 Core}. For a more
+    general introduction of the DOM implementation see the QDomDocument
+    documentation.
+
+    The QDom classes have a few issues of nonconformance with the XML
+    specifications that cannot be fixed in Qt 4 without breaking backward
+    compatibility. The QtXmlPatterns module and the QXmlStreamReader and
+    QXmlStreamWriter classes have a higher degree of a conformance.

+    Creates a document type node for the name \a qName.
+
+    \a publicId specifies the public identifier of the external
+    subset. If you specify an empty string (QString()) as the \a
+    publicId, this means that the document type has no public
+    identifier.
+
+    \a systemId specifies the system identifier of the external
+    subset. If you specify an empty string as the \a systemId, this
+    means that the document type has no system identifier.
+
+    Since you cannot have a public identifier without a system
+    identifier, the public identifier is set to an empty string if
+    there is no system identifier.
+
+    DOM level 2 does not support any other document type declaration
+    features.
+
+    The only way you can use a document type that was created this
+    way, is in combination with the createDocument() function to
+    create a QDomDocument with this document type.
+
+    In the DOM specification, this is the only way to create a non-null
+    document. For historical reasons, Qt also allows to create the
+    document using the default empty constructor. The resulting document
+    is null, but becomes non-null when a factory function, for example
+    QDomDocument::createElement(), is called. The document also becomes

+    \brief The QDomNodeList class is a list of QDomNode objects.
+
+    \inmodule QtXml
+    \ingroup xml-tools
+
+    Lists can be obtained by QDomDocument::elementsByTagName() and
+    QDomNode::childNodes(). The Document Object Model (DOM) requires
+    these lists to be "live": whenever you change the underlying
+    document, the contents of the list will get updated.
+
+    You can get a particular node from the list with item(). The
+    number of items in the list is returned by length().
+
+    For further information about the Document Object Model see
+    \l{http://www.w3.org/TR/REC-DOM-Level-1/}{Level 1} and
+    \l{http://www.w3.org/TR/DOM-Level-2-Core/}{Level 2 Core}.
+    For a more general introduction of the DOM implementation see the
+    QDomDocument documentation.

+    \class QDomNode
+    \reentrant
+    \brief The QDomNode class is the base class for all the nodes in a DOM tree.
+
+    \inmodule QtXml
+    \ingroup xml-tools
+    \mainclass
+
+    Many functions in the DOM return a QDomNode.
+
+    You can find out the type of a node using isAttr(),
+    isCDATASection(), isDocumentFragment(), isDocument(),
+    isDocumentType(), isElement(), isEntityReference(), isText(),
+    isEntity(), isNotation(), isProcessingInstruction(),
+    isCharacterData() and isComment().
+
+    A QDomNode can be converted into one of its subclasses using
+    toAttr(), toCDATASection(), toDocumentFragment(), toDocument(),
+    toDocumentType(), toElement(), toEntityReference(), toText(),
+    toEntity(), toNotation(), toProcessingInstruction(),
+    toCharacterData() or toComment(). You can convert a node to a null
+    node with clear().
+
+    Copies of the QDomNode class share their data using explicit
+    sharing. This means that modifying one node will change all
+    copies. This is especially useful in combination with functions
+    which return a QDomNode, e.g. firstChild(). You can make an
+    independent (deep) copy of the node with cloneNode().
+
+    A QDomNode can be null, much like a null pointer. Creating a copy
+    of a null node results in another null node. It is not
+    possible to modify a null node, but it is possible to assign another,
+    possibly non-null node to it. In this case, the copy of the null node
+    will remain null. You can check if a QDomNode is null by calling isNull().
+    The empty constructor of a QDomNode (or any of the derived classes) creates
+    a null node.
+
+    Nodes are inserted with insertBefore(), insertAfter() or
+    appendChild(). You can replace one node with another using
+    replaceChild() and remove a node with removeChild().
+
+    To traverse nodes use firstChild() to get a node's first child (if
+    any), and nextSibling() to traverse. QDomNode also provides
+    lastChild(), previousSibling() and parentNode(). To find the first
+    child node with a particular node name use namedItem().
+
+    To find out if a node has children use hasChildNodes() and to get
+    a list of all of a node's children use childNodes().
+
+    The node's name and value (the meaning of which varies depending
+    on its type) is returned by nodeName() and nodeValue()
+    respectively. The node's type is returned by nodeType(). The
+    node's value can be set with setNodeValue().
+
+    The document to which the node belongs is returned by
+    ownerDocument().
+
+    Adjacent QDomText nodes can be merged into a single node with
+    normalize().
+
+    \l QDomElement nodes have attributes which can be retrieved with
+    attributes().
+
+    QDomElement and QDomAttr nodes can have namespaces which can be
+    retrieved with namespaceURI(). Their local name is retrieved with
+    localName(), and their prefix with prefix(). The prefix can be set
+    with setPrefix().
+
+    You can write the XML representation of the node to a text stream
+    with save().
+
+    The following example looks for the first element in an XML document and
+    prints the names of all the elements that are its direct children.
+    \snippet doc/src/snippets/code/src_xml_dom_qdom.cpp 1

+    \l{http://www.w3.org/TR/REC-DOM-Level-1/}{Level 1} and
+    \l{http://www.w3.org/TR/DOM-Level-2-Core/}{Level 2 Core}.

+    \class QDomNamedNodeMap
+    \reentrant
+    \brief The QDomNamedNodeMap class contains a collection of nodes
+    that can be accessed by name.
+
+    \inmodule QtXml
+    \ingroup xml-tools
+
+    Note that QDomNamedNodeMap does not inherit from QDomNodeList.
+    QDomNamedNodeMaps do not provide any specific node ordering.
+    Although nodes in a QDomNamedNodeMap may be accessed by an ordinal
+    index, this is simply to allow a convenient enumeration of the
+    contents of a QDomNamedNodeMap, and does not imply that the DOM
+    specifies an ordering of the nodes.
+
+    The QDomNamedNodeMap is used in three places:
+    \list 1
+    \i QDomDocumentType::entities() returns a map of all entities
+        described in the DTD.
+    \i QDomDocumentType::notations() returns a map of all notations
+        described in the DTD.
+    \i QDomNode::attributes() returns a map of all attributes of an
+        element.
+    \endlist
+
+    Items in the map are identified by the name which QDomNode::name()
+    returns. Nodes are retrieved using namedItem(), namedItemNS() or
+    item(). New nodes are inserted with setNamedItem() or
+    setNamedItemNS() and removed with removeNamedItem() or
+    removeNamedItemNS(). Use contains() to see if an item with the
+    given name is in the named node map. The number of items is
+    returned by length().
+
+    Terminology: in this class we use "item" and "node"
+    interchangeably.

+    removeAttribute(). There are namespace-aware equivalents to these
+    functions, i.e. setAttributeNS(), setAttributeNodeNS() and
+    removeAttributeNS().
+
+    If you want to access the text of a node use text(), e.g.
+    \snippet doc/src/snippets/code/src_xml_dom_qdom.cpp 9
+    The text() function operates recursively to find the text (since
+    not all elements contain text). If you want to find all the text
+    in all of a node's children, iterate over the children looking for
+    QDomText nodes, e.g.
+    \snippet doc/src/snippets/code/src_xml_dom_qdom.cpp 10
+    Note that we attempt to convert each node to a text node and use
+    text() rather than using firstChild().toText().data() or
+    n.toText().data() directly on the node, because the node may not
+    be a text element.
+
+    You can get a list of all the decendents of an element which have
+    a specified tag name with elementsByTagName() or
+    elementsByTagNameNS().
+
+    To browse the elements of a dom document use firstChildElement(), lastChildElement(),
+    nextSiblingElement() and previousSiblingElement(). For example, to iterate over all
+    child elements called "entry" in a root element called "database", you can use:
+    \snippet doc/src/snippets/code/src_xml_dom_qdom.cpp 11
+

+    \class QDomDocument
+    \reentrant
+    \brief The QDomDocument class represents an XML document.
+
+    \inmodule QtXml
+    \mainclass
+    \ingroup xml-tools
+
+    The QDomDocument class represents the entire XML document.
+    Conceptually, it is the root of the document tree, and provides
+    the primary access to the document's data.
+
+    Since elements, text nodes, comments, processing instructions,
+    etc., cannot exist outside the context of a document, the document
+    class also contains the factory functions needed to create these
+    objects. The node objects created have an ownerDocument() function
+    which associates them with the document within whose context they
+    were created. The DOM classes that will be used most often are
+    QDomNode, QDomDocument, QDomElement and QDomText.
+
+    The parsed XML is represented internally by a tree of objects that
+    can be accessed using the various QDom classes. All QDom classes
+    only \e reference objects in the internal tree. The internal
+    objects in the DOM tree will get deleted once the last QDom
+    object referencing them and the QDomDocument itself are deleted.
+
+    Creation of elements, text nodes, etc. is done using the various
+    factory functions provided in this class. Using the default
+    constructors of the QDom classes will only result in empty
+    objects that cannot be manipulated or inserted into the Document.
+
+    The QDomDocument class has several functions for creating document
+    data, for example, createElement(), createTextNode(),
+    createComment(), createCDATASection(),
+    createProcessingInstruction(), createAttribute() and
+    createEntityReference(). Some of these functions have versions
+    that support namespaces, i.e. createElementNS() and
+    createAttributeNS(). The createDocumentFragment() function is used
+    to hold parts of the document; this is useful for manipulating for
+    complex documents.
+
+    The entire content of the document is set with setContent(). This
+    function parses the string it is passed as an XML document and
+    creates the DOM tree that represents the document. The root
+    element is available using documentElement(). The textual
+    representation of the document can be obtained using toString().
+
+    It is possible to insert a node from another document into the
+    document using importNode().
+
+    You can obtain a list of all the elements that have a particular
+    tag with elementsByTagName() or with elementsByTagNameNS().
+
+    The QDom classes are typically used as follows:
+    \snippet doc/src/snippets/code/src_xml_dom_qdom.cpp 16
+
+    Once \c doc and \c elem go out of scope, the whole internal tree
+    representing the XML document is deleted.
+
+    To create a document using DOM use code like this:
+    \snippet doc/src/snippets/code/src_xml_dom_qdom.cpp 17
+
+    For further information about the Document Object Model see
+    the Document Object Model (DOM)
+    \l{http://www.w3.org/TR/REC-DOM-Level-1/}{Level 1} and
+    \l{http://www.w3.org/TR/DOM-Level-2-Core/}{Level 2 Core}

+
+    If \a namespaceProcessing is true, the parser recognizes
