1. Identifier
2. Identifier.use
Fixed Value	official
3. Identifier.system
Control	10..1
Fixed Value	http://cvr.dk
4. Identifier.value
Control	10..1
Invariants	Defined on this element CVR-length: CVR must be exactly 8 numeric characters long (: value.matches('^[0-9]{8}$')) CVR-modulus-11: CVR must pass the modulus 11 check (: (( (value.substring(0,1).toInteger()2)+ (value.substring(1,1).toInteger()7)+ (value.substring(2,1).toInteger()6)+ (value.substring(3,1).toInteger()5)+ (value.substring(4,1).toInteger()4)+ (value.substring(5,1).toInteger()3)+ (value.substring(6,1).toInteger()2)+ (value.substring(7,1).toInteger()1)) mod(11)=0))

1. Identifier
Definition	An identifier - identifies some entity uniquely and unambiguously. Typically this is used for business identifiers.
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 (: hasValue() or (children().count() > id.count()))
2. Identifier.use
Definition	The purpose of this identifier.
Control	0..1
Binding	The codes SHALL be taken from IdentifierUse Identifies the purpose for this identifier, if known .
Type	code
Is Modifier	true
Summary	true
Requirements	Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers.
Comments	Applications can assume that an identifier is permanent unless it explicitly says that it is temporary.
Fixed Value	official
Invariants	Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
3. Identifier.system
Definition	Establishes the namespace for the value - that is, a URL that describes a set values that are unique.
Control	10..1
Type	uri
Summary	true
Requirements	There are many sets of identifiers. To perform matching of two identifiers, we need to know what set we're dealing with. The system identifies a particular set of unique identifiers.
Comments	Identifier.system is always case sensitive.
Fixed Value	http://cvr.dk
Example	General:http://www.acme.com/identifiers/patient
Invariants	Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
4. Identifier.value
Definition	The portion of the identifier typically relevant to the user and which is unique within the context of the system.
Control	10..1
Type	string
Summary	true
Comments	If the value is a full URI, then the system SHALL be urn:ietf:rfc:3986. The value's primary purpose is computational mapping. As a result, it may be normalized for comparison purposes (e.g. removing non-significant whitespace, dashes, etc.) A value formatted for human display can be conveyed using the Rendered Value extension. Identifier.value is to be treated as case sensitive unless knowledge of the Identifier.system allows the processer to be confident that non-case-sensitive processing is safe.
Example	General:123456
Invariants	Defined on this element CVR-length: CVR must be exactly 8 numeric characters long (: value.matches('^[0-9]{8}$')) CVR-modulus-11: CVR must pass the modulus 11 check (: (( (value.substring(0,1).toInteger()2)+ (value.substring(1,1).toInteger()7)+ (value.substring(2,1).toInteger()6)+ (value.substring(3,1).toInteger()5)+ (value.substring(4,1).toInteger()4)+ (value.substring(5,1).toInteger()3)+ (value.substring(6,1).toInteger()2)+ (value.substring(7,1).toInteger()1)) mod(11)=0)) ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))

Guidance on how to interpret the contents of this table can be found here.

1. Identifier
Definition	An identifier - identifies some entity uniquely and unambiguously. Typically this is used for business identifiers.
Control	0..* This element is affected by the following invariants: ele-1
2. Identifier.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
XML Representation	In the XML format, this property is represented as an attribute.
Summary	false
3. Identifier.extension
Definition	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.
Control	0..*
Type	Extension
Summary	false
Alternate Names	extensions, user content
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.
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())
Slicing	This element introduces a set of slices on Identifier.extension. The slices are unordered and Open, and can be differentiated using the following discriminators: value @ url
4. Identifier.use
Definition	The purpose of this identifier.
Control	0..1
Binding	The codes SHALL be taken from IdentifierUse Identifies the purpose for this identifier, if known
Type	code
Is Modifier	true
Summary	true
Requirements	Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers.
Comments	Applications can assume that an identifier is permanent unless it explicitly says that it is temporary.
Fixed Value	official
Invariants	Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
5. Identifier.type
Definition	A coded type for the identifier that can be used to determine which identifier to use for a specific purpose.
Control	0..1
Binding	The codes SHALL be taken from Identifier Type Codes; other codes may be used where these codes are not suitable A coded type for an identifier that can be used to determine which identifier to use for a specific purpose
Type	CodeableConcept
Summary	true
Requirements	Allows users to make use of identifiers when the identifier system is not known.
Comments	This element deals only with general categories of identifiers. It SHOULD not be used for codes that correspond 1..1 with the Identifier.system. Some identifiers may fall into multiple categories due to common usage. Where the system is known, a type is unnecessary because the type is always part of the system definition. However systems often need to handle identifiers where the system is not known. There is not a 1:1 relationship between type and system, since many different systems have the same type.
Invariants	Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
6. Identifier.system
Definition	Establishes the namespace for the value - that is, a URL that describes a set values that are unique.
Control	1..1
Type	uri
Summary	true
Requirements	There are many sets of identifiers. To perform matching of two identifiers, we need to know what set we're dealing with. The system identifies a particular set of unique identifiers.
Comments	Identifier.system is always case sensitive.

Invariants	Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
7. Identifier.value
Definition	The portion of the identifier typically relevant to the user and which is unique within the context of the system.
Control	1..1
Type	string
Summary	true

Definition	Time period during which identifier is/was valid for use.
Control	0..1

Invariants	Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
