Request for feedback/help with new example topics about expansion modules

I got stuck yesterday as I tested the example topics in the spec
      for implementing expansion modules using DTD:

    
      
Topic about adding attributes to certain elements: Tested,
        changed some details in the topic, verified that it worked

      
Topic about adding a new specialized element to the content
        model for a base element: Tested, tweaked, retweaked, but I am
        still getting failure. The scenario is one that Chris Nitchie
        outlined about adding a new element (<sectionDesc>) to the
        content model of <section>.

    
    I need active help with this in order to keep progress on the stage
    three proposal for issue #15, "Loosen specialization rules" moving
    forward.

    
And many thanks to Eliot for his active work with me week before
      last on ensuring that our (new, authored by me for DITA 2.0)
      example topics about implementing constraints using RNG worked.
