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.
