Oh yeah -- "simple" :p 

So, the full example (with organizer) at least "makes sense" to me conceptually, though it doesn't seem to match what's described [here](http://cdatools.org/infocenter/index.jsp?topic=%2Forg.openhealthtools.mdht.uml.cda.hitsp.doc%2Fclasses%2FDiagnosticResultsSection.html) (which seems to put "Procedure" entries right up at the top level of a Diagnostic Results section, rather than down inside organizers).

No matter -- this kind of confusion is exactly reason that MU2 moves away from C32. Too much ambiguity, too many different ways to interpret the spec.
