1.Extension
Definition
An Extension
Optional Extension Element - found in all resources.
Control0..1* 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 (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists())
2.Extension.url
Definition
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.
Fixed Value http://hl7.org/fhir/uv/security-label-ds4p/StructureDefinition/extension-sec-label-basis
3.Extension.value[x]
Definition
Value of extension - must be one of a constrained set of the data types (see Extensibility for a list).
Invariants Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
Slicing This element introduces a set of slices on Extension.value[x]. The slices are unordered and Closed, and can be differentiated using the following discriminators:
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.
