0. Identifier
2. Identifier.system

4. Identifier.value
Control	1..?
Invariants	oid-start: value must start with urn:oid: (`value.startsWith('urn:oid:')`)

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

0. Identifier
Definition	An identifier - identifies some entity uniquely and unambiguously. Typically this is used for business identifiers.
Short	An identifier intended for computation
Control	0..* This element is affected by the following invariants: ele-1
Is Modifier	false
Invariants	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.
Short	usual \| official \| temp \| secondary \| old (If known)
Comments	Applications can assume that an identifier is permanent unless it explicitly says that it is temporary.
Control	0..1
Binding	The codes SHALL be taken from IdentifierUsehttp://hl7.org/fhir/ValueSet/identifier-use\|4.0.1 (required to `http://hl7.org/fhir/ValueSet/identifier-use\|4.0.1`) Identifies the purpose for this identifier, if known .
Type	code
Is Modifier	true because This is labeled as "Is Modifier" because applications should not mistake a temporary id for a permanent one.
Primitive Value	This primitive element may be present, or absent, or replaced by an extension
Summary	true
Requirements	Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers.
Invariants	ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
4. Identifier.system
Definition	Establishes the namespace for the value - that is, a URL that describes a set values that are unique.
Short	The namespace for the identifier value
Comments	Identifier.system is always case sensitive.
Control	10..1
Type	uri
Is Modifier	false
Primitive Value	This primitive element may be present, or absent, or replaced by an extension
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.
Fixed Value	`urn:ietf:rfc:3986`
Example	<br/><b>General</b>:http://www.acme.com/identifiers/patient
Invariants	ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
6. Identifier.value
Definition	The portion of the identifier typically relevant to the user and which is unique within the context of the system.
Short	The value that is unique
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.
Control	10..1
Type	string
Is Modifier	false
Primitive Value	This primitive element may be present, or absent, or replaced by an extension
Summary	true
Example	<br/><b>General</b>:123456
Invariants	ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) oid-start: value must start with urn:oid: (`value.startsWith('urn:oid:')`)

0. Identifier
Definition	An identifier - identifies some entity uniquely and unambiguously. Typically this is used for business identifiers.
Short	An identifier intended for computation
Control	0..* This element is affected by the following invariants: ele-1
Is Modifier	false
Invariants	ele-1: All FHIR elements must have a @value or children (`hasValue() or (children().count() > id.count())`)
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.
Short	Unique id for inter-element referencing
Control	0..1
Type	string
Is Modifier	false
XML Format	In the XML format, this property is represented as an attribute.
Summary	false
4. 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.
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..*
Type	Extension
Is Modifier	false
Summary	false
Alternate Names	extensions, user content
Invariants	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 areUnordered and Open, and can be differentiated using the following discriminators: value @ url
6. Identifier.use
Definition	The purpose of this identifier.
Short	usual \| official \| temp \| secondary \| old (If known)
Comments	Applications can assume that an identifier is permanent unless it explicitly says that it is temporary.
Control	0..1
Binding	The codes SHALL be taken from IdentifierUse (required to `http://hl7.org/fhir/ValueSet/identifier-use\|4.0.1`) Identifies the purpose for this identifier, if known .
Type	code
Is Modifier	true because This is labeled as "Is Modifier" because applications should not mistake a temporary id for a permanent one.
Primitive Value	This primitive element may be present, or absent, or replaced by an extension
Summary	true
Requirements	Allows the appropriate identifier for a particular context of use to be selected from among a set of identifiers.
Invariants	ele-1: All FHIR elements must have a @value or children (`hasValue() or (children().count() > id.count())`)
8. Identifier.type
Definition	A coded type for the identifier that can be used to determine which identifier to use for a specific purpose.
Short	Description of identifier
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.
Control	0..1
Binding	Unless not suitable, these codes SHALL be taken from Identifier Type Codes (extensible to `http://hl7.org/fhir/ValueSet/identifier-type`) A coded type for an identifier that can be used to determine which identifier to use for a specific purpose.
Type	CodeableConcept
Is Modifier	false
Summary	true
Requirements	Allows users to make use of identifiers when the identifier system is not known.
Invariants	ele-1: All FHIR elements must have a @value or children (`hasValue() or (children().count() > id.count())`)
10. Identifier.system
Definition	Establishes the namespace for the value - that is, a URL that describes a set values that are unique.
Short	The namespace for the identifier value
Comments	Identifier.system is always case sensitive.
Control	1..1
Type	uri
Is Modifier	false
Primitive Value	This primitive element may be present, or absent, or replaced by an extension
