The value of the extension is a uri the 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: * todo.",
