When you complete the steps, the page template should look similar to this in the visual editor:
The links you created are the menu items that will appear on every page, and will navigate to the three pages in your task flow. The action property of each link corresponds to the outcome properties of the control flow cases on your task flow diagram.
The facet you defined,
main_content, will be used for page content. Page template facets define areas on the template where content can be added by page authors when they use the template to create their JSF pages. To allow page authors to add their own content, you define one or more facets as placeholders for future content.
