Cross-version Extension for R4.Extension.value[x] for use in FHIR R4B
This cross-version extension represents Extension.value[x] from http://hl7.org/fhir/StructureDefinition/Extension|4.0.1 for use in FHIR R4B.
Value of extension - must be one of a constrained set of the data types (see [Extensibility](https://hl7.org/fhir/extensibility.html) for a list).
`Extension.value[x]` maps to R4B `Extension.value[x]`. Type `Meta` has no mapping So is mapped as SourceIsBroaderThanTarget.
All FHIR elements must have a @value or children unless an empty Parameters resource
hasValue() or (children().count() > id.count()) or $this is Parameters
Must have either extensions or value[x], not both
exists(f:extension)!=exists(f:*[starts-with(local-name(.), 'value')])
Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Extensions are always sliced by (at least) url
All FHIR elements must have a @value or children
hasValue() or (children().count() > id.count())
exists(f:extension)!=exists(f:*[starts-with(local-name(.), "value")])
The version specific identifier, as it appears in the version portion of the URL. This value changes when the resource is created, updated, or deleted.
Additional content defined by implementations
May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
Source of the definition for the extension code - a logical name or a URL.
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.
When the resource last changed - e.g. when the version changed.
Identifies where the resource comes from
A uri that identifies the source system of the resource. This provides a minimal amount of [Provenance](https://hl7.org/fhir/p.html#) information that can be used to track or differentiate the source of information in the resource. The source may identify another FHIR server, document, message, database, etc.
Profiles this resource claims to conform to
A list of profiles (references to [StructureDefinition](https://hl7.org/fhir/s.html#) resources) that this resource claims to conform to. The URL is a reference to [StructureDefinition.url](https://hl7.org/fhir/structuredefinition-defi.html#StructureDefinition.url).
Security Labels applied to this resource
Security labels applied to this resource. These tags connect specific resources to the overall security policy and infrastructure.
Security Labels from the Healthcare Privacy and Security Classification System.
Tags applied to this resource. Tags are intended to be used to identify and relate resources to process and workflow, and applications are not required to consider the tags when interpreting the meaning of a resource.
Codes that represent various types of tags, commonly workflow-related; e.g. "Needs review by Dr. Jones".
Data type name for Extension.value[x] from FHIR R4
Value of extension - must be one of a constrained set of the data types (see [Extensibility](http://hl7.org/fhir/R5/extensibility.html) for a list).
