Motivation
You want to add a new instance or element from a template. You want to do a deep copy of complex XML from one instance to another instance within a model.
Method
We will use the XForms xf:insert element with the origin attribute set to the source instance. We will use the nodeset attribute to indicate where the data should be copied to.
