//: DOM Document Fragment class.
//- !group=Core/XML!
//- !header=core.h!
//- <p>DocumentFragment is a "lightweight" or "minimal" 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 Document object could fulfil 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.</p>
//- <p>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.</p>
//- <p>The children of a DocumentFragment node are zero or more nodes
//- representing the tops of any sub-trees defining the structure of the
//- document. 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
//- 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.</p>
//- <p>When a DocumentFragment is inserted into a Document (or indeed any
//- other Node that may take children) the children of the DocumentFragment
//- and not the DocumentFragment itself are inserted into the Node. This
//- makes the DocumentFragment very useful when the user wishes to create
//- nodes that are siblings; the DocumentFragment acts as the parent of these
//- nodes so that the user can use the standard methods from the Node interface,
//- such as insertBefore() and appendChild().</p>
