Detailed Descriptions for the elements in the extension.
Extension | |
Definition | Human readable names for the codesystem. |
Control | 0..* This element is affected by the following invariants: ele-1 |
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..* |
Type | Extension |
Slicing | This element introduces a set of slices. The slicing rules are:
|
Extension.extension(name) | |
Definition | This name is intended to be human readable, short and as specific as possible and to convey the purpose of the value set. It is considered to be the name of the value set. |
Control | 1..1 |
Type | Extension |
Comments | This need not be unique. However some use cases require uniqueness within a namespace and therefore best practice would be to make the name unique. |
Extension.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.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 SHALL be a URI for the Structure Definition defining the extension. |
Fixed Value | name |
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(preferred) | |
Definition | Flag that this Name in this Name Language is the preferred human-readable signifier in this language. |
Control | 0..1 |
Type | Extension |
Comments | There may be multiple human readable names in a given language, and this flag indicates which of them is preferred for the given language. |
Extension.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.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 SHALL be a URI for the Structure Definition defining the extension. |
Fixed Value | preferred |
Extension.extension.valueBoolean | |
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 | boolean |
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. |

Extension.value[x] | |
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). |
