The UI Param tag is used to pass objects as named variables between
Facelets. The name attribute of the UI Param tag should match the name attribute
of a ui:define tag
contained in a ui:composition or ui:decorate in the
template page receiving the object. The UI Param tag can also be used to pass
objects to another page by using the ui:include tag.
