Extension
Definition	A label for a particular group or question within the questionnaire.
Control	0..1

Control	0..1

Extension.url
Definition	Source of the definition for the extension code - a logical name or a URL.
Control	1..1
Type	uri
Comments	The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition should be version specific. This will ideally be the URI for the Resource Profile defining the extension, with the code for the extension after a #.
Fixed Value	http://hl7.org/fhir/StructureDefinition/questionnaire-label
Extension.valueString
Definition	Value of extension - may be a resource or one of a constrained set of the data types (see Extensibility in the spec for list).
