* Imports a node from another document to this document. The returned node

*
* For all nodes, importing a node creates a node object owned by the

* nodeName and nodeType, plus the attributes related to namespaces
* (prefix, localName, and namespaceURI).
*
* As in the cloneNode operation on a Node, the source node is not altered.
* Additional information is copied as appropriate to the nodeType,
* attempting to mirror the behavior expected if a fragment of XML or HTML
* source was copied from one document to another, recognizing that the two
* documents may have different DTDs in the XML case. The following list
* describes the specifics for each type of node.
*
* ATTRIBUTE_NODE
* The ownerElement attribute is set to null and the specified flag is set
* to true on the generated Attr. The descendants of the source Attr are
* recursively imported and the resulting nodes reassembled to form the
* corresponding subtree. Note that the deep parameter has no effect on
* Attr nodes; they always carry their children with them when imported.
*
* DOCUMENT_FRAGMENT_NODE
* If the deep option was set to true, the descendants of the source
* element are recursively imported and the resulting nodes reassembled to
* form the corresponding subtree. Otherwise, this simply generates an
* empty DocumentFragment.
*
* DOCUMENT_NODE
* Document nodes cannot be imported.
*
* DOCUMENT_TYPE_NODE
* DocumentType nodes cannot be imported.
*
* ELEMENT_NODE
* Specified attribute nodes of the source element are imported, and the
* generated Attr nodes are attached to the generated Element. Default
* attributes are not copied, though if the document being imported into
* defines default attributes for this element name, those are assigned. If
* the importNode deep parameter was set to true, the descendants of the
* source element are recursively imported and the resulting nodes
* reassembled to form the corresponding subtree.
*
* ENTITY_NODE
* Entity nodes can be imported, however in the current release of the DOM
* the DocumentType is readonly. Ability to add these imported nodes to a
* DocumentType will be considered for addition to a future release of the
* DOM.
* On import, the publicId, systemId, and notationName attributes are
* copied. If a deep import is requested, the descendants of the the source
* Entity are recursively imported and the resulting nodes reassembled to
* form the corresponding subtree.
*
* ENTITY_REFERENCE_NODE Only the EntityReference itself is copied, even if
* a deep import is requested, since the source and destination documents
* might have defined the entity differently. If the document being
* imported into provides a definition for this entity name, its value is
* assigned.
*
* NOTATION_NODE
* Notation nodes can be imported, however in the current release of the
* DOM the DocumentType is readonly. Ability to add these imported nodes to
* a DocumentType will be considered for addition to a future release of
* the DOM.
* On import, the publicId and systemId attributes are copied.
* Note that the deep parameter has no effect on Notation nodes since they
* never have any children.
*
* PROCESSING_INSTRUCTION_NODE
* The imported node copies its target and data values from those of the
* source node.
*
* TEXT_NODE, CDATA_SECTION_NODE, COMMENT_NODE
* These three types of nodes inheriting from CharacterData copy their data
* and length attributes from those of the source node.
*
* @param importedNode The node to import.
*
* @param deep If true, recursively import the subtree under the specified
* node; if false, import only the node itself, as explained above. This
* has no effect on Attr, EntityReference, and Notation nodes.

/**
* \c DocumentFragment is a "lightweight" or "minimal"
* \c Document object. It is very common to want to be
* able to extract a portion of a document's tree or to create a new
* fragment of a document. Imagine implementing a user command like
* cut or rearranging a document by moving fragments around. It is
* desirable to have an object which can hold such fragments and it is
* quite natural to use a Node for this purpose. While it is true that
* a \c Document object could fulfil this role, a
* \c Document object can potentially be a heavyweight object,
* depending on the underlying implementation. What is really needed
* for this is a very lightweight object. \c DocumentFragment
* is such an object.
*
* Furthermore, various operations -- such as inserting nodes as
* children of another \c Node -- may take
* \c DocumentFragment objects as arguments; this results in all
* the child nodes of the \c DocumentFragment being moved
* to the child list of this node.
*
* The children of a \c DocumentFragment node are zero or
* more nodes representing the tops of any sub-trees defining the
* structure of the document. \c DocumentFragment nodes do
* not need to be well-formed XML documents (although they do need to
* follow the rules imposed upon well-formed XML parsed entities,
* which can have multiple top nodes). For example, a
* \c DocumentFragment might have only one child and that child
* node could be a \c Text node. Such a structure model
* represents neither an HTML document nor a well-formed XML document.
*
* When a \c DocumentFragment is inserted into a
* \c Document (or indeed any other \c Node that may
* take children) the children of the \c DocumentFragment
* and not the \c DocumentFragment itself are inserted
* into the \c Node . This makes the
* \c DocumentFragment very useful when the user wishes to create
* nodes that are siblings; the \c DocumentFragment acts
* as the parent of these nodes so that the user can use the standard
* methods from the \c Node interface, such as
* \c insertBefore() and \c appendChild() .
