In D2D rendering, we frequently climb the DOM tree looking for a parent container to consolidate a number of changes. In JSF, this parent container is typically a sub-class of UINamingContainer. Most of the time, this duty is handled by using <ice:form>. However, particularly in portlet environments, it would be useful to have a NamingContainer component that is simply a container (as opposed to something like a form which has lots of other complex behaviour) that can be used to wrap the entire contents of the portlet. The component could be very generic so that it can be used in many different scenarios (i.e. non-portlet) or it could be specifically for portlets only. Or there could be both: a generic container with a more specific portlet container. Other than taking the basic JSF attributes (like id, styleClass, etc) it doesn't need to have any special behaviour other then inheriting from UINamingContainer.
