If just the refis given the last element of the list is cloned and appended.
Important: if the list is empty this action has no effect! See below.
Fore differs from XForms in that it will clear the values of the cloned item as most of the time
that's what is wanted. To preserve the values add keep-values marker attribute.
When no origin attribute is given the last entry of the list is cloned and
inserted. This behavior is conformant with XForms 2.0.
Inserts an entry to the top of the list here.
With origin you can select nodes to be used as templates for insertion.
Inserts an item after the first in the list
No at given means we append the template to the list
inserts an item before the currently selected item.
Will copy the referenced node and insert it after it.
