0. Extension
Definition | An Extension Optional Extension Element - found in all resources.
Short | ExtensionOptional Extensions Element
Control | 0..* This element is affected by the following invariants: ele-1
Invariants | ele-1: All FHIR elements must have a @value or children (`hasValue() | (children().count() > id.count())`) ext-1: Must have either extensions or value[x], not both (`extension.exists() != value.exists()`) ele-1: All FHIR elements must have a @value or children (hasValue() | (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.
Short | identifies the meaning of the extension
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.
Control | 1..1
Type | uri
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
XML Format | In the XML format, this property is represented as an attribute.
Fixed Value | `http://hl7.org/fhir/4.0/StructureDefinition/extension-Meta.source`
4. 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).
Short | Value of extension
Control | 0..1
Type | uri, date, dateTime, Meta, code, string, Address, Attachment, integer, oid, Count, instant, ContactPoint, HumanName, Money, Identifier, Coding, markdown, SampledData, Ratio, id, positiveInt, Age, Distance, Reference, Period, Quantity, Duration, Range, Annotation, boolean, base64Binary, Signature, unsignedInt, time, Timing, decimal, CodeableConcept
[x] Note | SeeChoice of Data Typesfor further information about how to use [x]
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Slicing | This element introduces a set of slices on `Extension.value[x]`. The slices areUnordered and Closed, and can be differentiated using the following discriminators: type @ $this
6. Extension.value[x]:valueUri
Slice Name | valueUri
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).
Short | Value of extension
Control | 0..1
Binding | The codes SHOULD be taken from For codes, see Bronsysteem Zorgaanbieder (preferred to `http://fhir.hl7.nl/zorgviewer/ValueSet/bronsysteem-zorgaanbieder` )

0. Extension
Definition | An Extension
Short | Extension
Control | 0..* This element is affected by the following invariants: ele-1
Invariants | ele-1: All FHIR elements must have a @value or children (`hasValue() | (children().count() > id.count())`) ext-1: Must have either extensions or value[x], not both (`extension.exists() != value.exists()`)
2. 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.
Short | xml:id (or equivalent in JSON)
Control | 0..1
Type | string
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
XML Format | In the XML format, this property is represented as an attribute.
4. Extension.extension
Definition | May be used to represent additional information that is not part of the basic definition of the element. In order 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 is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
Short | Additional Content defined by implementations
Comments | 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.
Control | 0..*
