nodeInsertBeforeDocFragment
NIST
If the "newChild" is a DocumentFragment object then all
its children are inserted in the same order before the
the "refChild".
Create a DocumentFragment object and populate it with
two Element nodes. Retrieve the second employee and
insert the newly created DocumentFragment before its
fourth child. The second employee should now have two
extra children("newChild1" and "newChild2") at
positions fourth and fifth respectively.
