Detailed Descriptions for the elements in the extension.

Extension
Definition	A code specifying the type of probability distribution for the uncertainty.
Control	0..1 This element is affected by the following invariants: ele-1
Comments	This is only meaningful if there is also an uncertainty extension. If there is an uncertainty extension with no type, this means that the probability distribution type is unknown. In that case, the uncertainty has the meaning of an informal guess.
Invariants	Defined on this element ele-1: All FHIR elements must have a @value or children (xpath: @value\|f:\|h:div) ext-1: Must have either extensions or value[x], not both (xpath: exists(f:extension)!=exists(f:[starts-with(local-name(.), 'value')]))
Extension.id
Definition	unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Control	0..1
Type	string
Extension.extension
Definition	An Extension
Control	0..0
Type	Extension
Slicing	This element introduces a set of slices. The slicing rules are: unordered Open discriminators: value:url
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 SHALL be a URI for the Structure Definition defining the extension.
Fixed Value	http://hl7.org/fhir/StructureDefinition/iso21090-uncertaintyType
Extension.valueCode
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).
Control	0..1
Terminology Binding	Codes specifying the type of probability distribution The codes SHALL be taken from ProbabilityDistributionType
Type	code
