Curbing the shown level of a menu tree in an ADF page

Question

Hi,
I have a hierarchy of pages defined in my faces-config.xml as managed beans using the MenuModelAdapter, MenuTreeModelAdapter and MenuItem classes from the SR Demo/Tutorial.
On each page is an af:page component which has the menu model as its value. There is also an af:commandMenuItem component in the nodeStamp facet, mapped to the various values of the menu items.
Example Page
<af:page value="#{menu.model}" var="node">
  <f:facet name="nodeStamp">
    <af:commandMenuItem text="#{node.label}" action="#{node.getOutcome}"
      type="#{node.type}" icon="#{node.icon}"/>
  </f:facet>
  ... page content ...
</af:page>
...This all works the way it is supposed to (manifesting as global buttons, menu tabs, menu bar, etc. and highlighting the correct menu items). However, I would like to specify a maximum level that the hierarchy can be shown to (e.g. only show the menu tabs and menu bar, but not the side bar menu - 2 levels) but still have the correct parent menu items highlighted when visiting one of the pages not shown.
This is basically so that I can have a multi-page process that shows as being part of a section of the site, but is not accessible through the menu system.
Does anyone know how I might be able to do that?

Well at last I've been able to get this working. Unfortunately it's a bit of a hack.
I've explained it all in my blog and I've also uploaded a JDeveloper application with all my code and example pages.
