Definition
An absolute URI that is used to identify this expansion profile when it is referenced in a specification, model, design or an instance. This SHALL be a URL, SHOULD be globally unique, and SHOULD be an address at which this expansion profile is (or will be) published. The URL SHOULD include the major version of the expansion profile. For more information see [Technical and Business Versions](resource.html#versions).
Comment
Can be a urn:uuid: or a urn:oid:, but real http: addresses are preferred. Multiple instances may share the same url if they have a distinct version.

Allows the expansion profile to be referenced by a single globally unique identifier.

Comment
Typically, this is used for identifiers that can go in an HL7 V3 II (instance identifier) data type, e.g., to identify this expansion profile outside of FHIR, where it is not possible to use the logical URI.

Definition
A coded type for the identifier that can be used to determine which identifier to use for a specific purpose.
Comment
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.
Requirements
Allows users to make use of identifiers when the identifier system is not known.

Codes may be defined very casually in enumerations, or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information. Ordering of codings is undefined and SHALL NOT be used to infer meaning. Generally, at most only one of the coding values will be labeled as UserSelected = true.

However this cannot consistently be assured. and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged.
Comment
Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.

A reference to a location at which the other resource is found. The reference may be a relative reference, in which case it is relative to the service base URL, or an absolute URL that resolves to the location where the resource is found. The reference may be version specific or not. If the reference is not to a FHIR RESTful server, then it should be assumed to be version specific. Internal fragment references (start with '#') refer to contained resources.
Comment
Using absolute URLs provides a stable scalable approach suitable for a cloud/web context, while using relative/logical references provides a flexible approach suitable for use when trading across closed eco-system boundaries. Absolute URLs do not need to point to a FHIR RESTful server, though this is the preferred approach. If the URL conforms to the structure "/[type]/[id]" then it should be assumed that the reference is to a FHIR RESTful server.

Path
ExpansionProfile.identifier.Identifier.assigner.Reference.identifier

Reference.identifier
Type
Cardinality
0 - 1
Definition
An identifier for the other resource. This is used when there is no way to reference the other resource directly, either because the entity is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference.
Comment
When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy.
When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference
Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it.

Definition
The version of the code system which was used when choosing this code. Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured. and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged.
Comment
Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.

Indicates that this coding was chosen by a user directly - i.e. off a pick list of available items (codes or displays).
Comment
Amongst a set of alternatives, a directly chosen code is the most appropriate starting point for new translations. There is some ambiguity about what exactly 'directly chosen' implies, and trading partner agreement may be needed to clarify the use of this element and its consequences more completely.
Requirements
This has been identified as a clinical safety criterium - that this exact system/code pair was chosen explicitly, rather than inferred by the system based on some rules or language processing.

This is used to apply version specifc exclusion contraints. If no version is specified, then all codes from the code system present in the expansion (prior to application of the expansion profile) will be excluded.

The ValueSet defintion refers to all fields in the ValueSet definition apart from ValueSet.contains. The definition is only included if includeDefinition is present and has a value of "true".

Comment
Inactive codes are included if activeOnly is present and has a value of "true". Note that if the value set explicitly specifies that inactive codes are included, this property can still remove them from a specific expansion, but this parameter cannot include them if the value set excludes them.

Nesting of codes is excluded if excludeNested is present and has a value of "true".

Heirahical contains are useful for UI use, but not when validating. Code Generation etc. may depend on context.

If the value set being expanded is incomplete (because it is too big to expand), return a limited expansion (a subset) with an indicator that expansion is incomplete, using the extension [http://hl7.org/fhir/StructureDefinition/valueset-toocostly](extension-valueset-toocostly.html).
Comment
This field overides the default behaviour (which is to return an error). This does not apply to expansions which are unbounded. Clients SHALL process the extension [http://hl7.org/fhir/StructureDefinition/valueset-toocostly](extension-valueset-toocostly.html) correctly if limitedExpansion = true.
