  <description value="This extension associates a structure definition with a data dictionary - a collection
   of data elements that any instance of data that conforms to the structure definition must
   also conform to. The value of the extension is a uri that defines a query that identifies
   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
   Data Element

For Questionnaire:
