The Purchase Order Dynamic.xdp sample form uses fragments to configure the footer to display the correct address, depending on the data being merged with the form. When the sample form is merged with the Purchase Order Canada.xml file, the FooterCanada fragment is instantiated; however, when the form is merged with the Purchase Order US.xml file, the FooterUS is instantiated.
