Extension Who has used and how? - Detailed Descriptions

Detailed Descriptions for the elements in the extension.

Extension
Definition	Consumers of the value set and the implementations, projects or standards that the author has utilized the value set in.
Control	0..*
Type	Extension
Comments	This is likely to be a ???point in time??? view and should not be considered an authoritative listing of all uses of the value set.
Extension.id
Definition	unique id for the element within a resource (for internal references).
Control	0..1
Type	id
Extension.extension
Definition	An Extension
Control	0..*
Type	Extension
Slicing	This element introduces a set of slices. The slicing rules are: unordered Open discriminators: url
Extension.extension(user)
Definition	This is most likely to be an organization but can be an individual. It would not be a program, that information should be recorded in the usage.use.
Control	1..1
Type	Extension
Extension.extension.id
Definition	unique id for the element within a resource (for internal references).
Control	0..1
Type	id
Extension.extension.extension(extension)
Definition	An Extension
Control	0..0
Type	Extension
Extension.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	user
Extension.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).
Control	1..1
Type	string
Extension.extension(use)
Definition	A descriptive name of the project or standard in which the value set is used.
