Actually, inserting a DocumentFragment 'node' into a tree should insert the
child nodes of the DocumentFragment (leaving it empty).

HERARCHY_REQUEST_ERR exception should be thrown only if any of the child
nodes can not be inserted.  State of the tree after partially sucessful
DocumentFragment insertion is unspecified in the spec.  My implementation
revokes the entire operation leaving the tree and the DocumentFragment
unchanged.
