   the collection of relevant data elements  This extension can be used on any structure
   definition that is a constraint on the resource types Observation and Questionnaire. THe
   profile specifies which elements are mandatory etc., but any elements in a resource that
   conforms to the structure definition must also conform to one of the defined data elements.
    For Observation: * Observation.code must be associated with a matching Data Element by
   DataElement.code.  * The structure definition should bind Observation.code to a value
   set that has the same codes as the collection of data elements (though it can be narrower)
   * the unit and the quantity value should conform to the rules laid down in the matching
