Creating a Page Template
You can create a JSF page template from the New Gallery by selecting Web Tier > JSF > JSF Page Template. You give it a file name, and optionally a different page template name. You can optionally select to create an associated page definition file as well.
The Create JSF Page Template dialog box also enables you to create:
Facet definitions: Placeholders for content to be provided by page developers
Attributes: Attributes that can be referenced from the template; abstraction between data provided on the page and that used by the page
Model parameters: Parameters in the page definition file that are passed differently from attributes
