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

1. Extension
Definition	A set of codes advising a system or user which name in a set of names to select for a given purpose. Optional Extension Element - found in all resources.
Control	0..1*
Comments	A name without specific use code might be a default name useful for any purpose, but a name with a specific use code would be preferred for that respective purpose.
2. Extension.extension
Control	0..0*
3. Extension.url
Fixed Value	http://hl7.org/fhir/StructureDefinition/iso21090-EN-use
4. Extension.value[x]
Control	10..1
Binding	The codes SHALL be taken from EntityNameUseR2For codes, see (unbound)
Type	Choice of: , date, Meta, Address, Attachment, integer, Count, DataRequirement, Dosage, uuid, Identifier, RatioRange, Coding, SampledData, id, positiveInt, Distance, Availability, integer64, Period, Duration, canonical, Range, RelatedArtifact, base64Binary, UsageContext, Timing, decimal, ExtendedContactDetail, CodeableConcept, ParameterDefinition, dateTime, string, oid, instant, ContactPoint, HumanName, Money, markdown, Ratio, Age, Reference, TriggerDefinition, Quantity, uri, url, Annotation, ContactDetail, boolean, Expression, CodeableReference, Signature, unsignedInt, time
[x] Note	See Choice of Data Types for further information about how to use [x]

1. Extension
Definition	A set of codes advising a system or user which name in a set of names to select for a given purpose. Optional Extension Element - found in all resources.
Control	0..1*
Comments	A name without specific use code might be a default name useful for any purpose, but a name with a specific use code would be preferred for that respective purpose.
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.extension
Definition	An Extension 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 managable, 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..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 Extension.extension. The slices are unordered and Open, and can be differentiated using the following discriminators: value @ url
3. Extension.url
Definition	Source of the definition for the extension code - a logical name or a URL.
Control	1..1
Type	uri
XML Representation	In the XML format, this property is represented as an attribute.
Summary	false
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.
Fixed Value	http://hl7.org/fhir/StructureDefinition/iso21090-EN-use
4. Extension.value[x]
Definition	Value of extension - must be one of a constrained set of the data types (see Extensibility for a list).
Control	10..1 This element is affected by the following invariants: ext-1
Binding	The codes SHALL be taken from EntityNameUseR2For codes, see (unbound)
Type	Choice of: code, date, Meta, Address, Attachment, integer, Count, DataRequirement, Dosage, uuid, Identifier, RatioRange, Coding, SampledData, id, positiveInt, Distance, Availability, integer64, Period, Duration, canonical, Range, RelatedArtifact, base64Binary, UsageContext, Timing, decimal, ExtendedContactDetail, CodeableConcept, ParameterDefinition, dateTime, string, oid, instant, ContactPoint, HumanName, Money, markdown, Ratio, Age, Reference, TriggerDefinition, Quantity, uri, url, Annotation, ContactDetail, boolean, Expression, CodeableReference, Signature, unsignedInt, time
[x] Note	See Choice of Data Types for further information about how to use [x]
