Release 5.4.0

FHIR-43595: Improve change tracking in the extension registry
The DocumentReference extensions documentreference-sourcepatient and documentreference-thumbnail are now owned by FHIR Infrastructure (previously Orders and Observations)
FHIR-59432: Mark artifact-versionAlgorithm, elementdefinition-suppress, patient-sexParameterForClinicalUse, quantity-confidenceInterval, questionnaire-derivationType, rdf-concept-iri and structuredefinition-imposeProfile as active
FHIR-57719: Add CapabilityStatement.instantiates as a context for the Conformance expectation extension
FHIR-57837: The minimum value of the maxOccurs extension is now 2 (a repeating item must allow at least 2 repetitions)
FHIR-57839: The minimum value of the minOccurs extension is now 1 (it only applies to required items)
FHIR-57563: New extension mediaRepresentation - a media representation (e.g. a scanned fax, an audio clip) of the target of a Reference or canonical. Media is a target for the versions where it exists (R4B and earlier), using version-specific-use on the target profile
FHIR-56001: Add Ratio as a context for the rendered-value extension, for ratios with a preferred rendering (e.g. 33/99 shown as 1/3)
FHIR-53267: Add RelatedArtifact as a context for the package-source extension, so the source package of a dependency can be recorded during a dependency walk
FHIR-58610: New extensions additional-operation-context, additional-operation-parameter-allowedType and additional-operation-parameter-targetProfile, so an additional resource can supplement existing operation definitions
FHIR-57235: Add ValueSet.compose.include.concept as a context for the standards-status extension, so it can replace the deprecated valueset-deprecated extension there
FHIR-59372: The originalText extension notes that it can accompany a value or components, but can also be sent in place of a primitive value or components
FHIR-58619: New search parameter topic for the artifact-topic extension
FHIR-58616: New extension canonicalresource-alternateTitle (alternative human labels for an artifact, e.g. acronyms and short titles), and search parameter any-title that searches the title and alternate titles
FHIR-57615: New extension operationoutcome-resource - identifies the source resource related to an OperationOutcome or one of its issues (e.g. the resource that an issue.expression is rooted in)
FHIR-56002: New extensions attachment-thumbnail (a smaller version of the content of an Attachment, e.g. for preview) and attachment-isThumbnail (marks an Attachment in a repeating element as a low-resolution form of the content). The documentreference-thumbnail extension is deprecated in favour of attachment-isThumbnail
FHIR-44354: The workflow-protectiveFactor and workflow-barrier extensions note that they are not workflow-related despite their names, and protectiveFactor explains why its contexts are limited to prospective care
FHIR-57265: New extension contentReferenceProfile - a profile (element) that applies to an element defined by a contentReference, so that profile constraints on recursive elements such as Questionnaire.item can be applied at nested levels
FHIR-56953: The largeValue extension allows integer64 as well as decimal for its value
FHIR-56447: The package-source extension is marked (snapshot-behavior = ignore) so that it is not copied into derived profiles
FHIR-56412: New extension canonicalresource-suppressActor - identifies an actor that is not relevant for the current publication, so its obligations are not prominently shown in profile tables or used to determine key elements
FHIR-39327: In the relative-date extension, targetReference and targetCode are each optional, with an invariant that at least one is present, and documentation of how they combine
FHIR-55397: Clarified the obligation extension's applicable-number - it sets the minimum number of repetitions a system must support for that obligation - and documented how obligations apply to repeating elements
FHIR-55398: Documented how obligations can depend on context (clinical context, relevance, business rules) - via the usage property, slicing, profile scope, and implementation context
FHIR-52992: Removed CodeSystem.concept as a context for the standards-status extension - the status of a concept is represented using a concept property
FHIR-50851: New extension codesystem-reservedCodeSpace - describes a set of codes (by regular expression) that the code system steward has allocated for users to create their own codes
FHIR-53122: New extension valueset-scope - replaces the R5 ValueSet.scope element (inclusionCriteria, exclusionCriteria), which has been removed in R6
FHIR-40703: The valueset-compose-createdBy extension is now only for use up to R4B (4.3); from R5 on, use ValueSet.author
FHIR-40735: Clarified the descriptions of the codesystem-label and valueset-label extensions, including when to use each
FHIR-43081: New extension authorization-hint, with its code system and value set - a hint about the kind of authorization that applies
FHIR-54661: New extension nutritionorder-serviceCategory and search parameter serviceCategory - partitions a NutritionOrder into service categories for searching, access control and system behavior
FHIR-54631: New extension consent-provision-limit - limits on the permitted use of data released under a Consent provision
FHIR-54637: New extension consent-provision-expression - restricts a Consent provision to apply only when a FHIRPath or CQL expression evaluates to true
The Consent extensions (consent-NotificationEndpoint, consent-ResearchStudyContext, consent-Transcriber, consent-Witness, consent-location) are now owned by Security (previously Community Based Collaborative Care)
FHIR-57496: New extension rdf-concept-iri - the RDF concept IRI for a Coding
FHIR-54614: The Condition.bodySite and Procedure.bodySite contexts of the bodySite extension, and the Procedure context of the procedure-targetBodyStructure extension, are limited to R5 and earlier (R6 has the elements)
FHIR-53036: The device-alertDetection extension uses the device alert terminology in HL7 Terminology (THO); the devicealert-activationState, devicealert-priority and devicealert-condition code systems and value sets have been removed from this package
FHIR-56683: New extension device-conformsTo-source - the standard, regulation, certification, guidance or other publication that supports a Device.conformsTo claim
New extensions observation-supportingDevice and observationdefinition-supportingDevice - additional devices, kits or reagents (e.g. test kits, calibration kits, QC materials) used to generate a measurement. The Observation and DiagnosticReport contexts of event-statusReason are limited to R5 and earlier
FHIR-55462: New extension additional-resource-reference-target - allows a work group to indicate that a core element (or another additional resource) may refer to an additional resource using a normal Reference
FHIR-57039 and FHIR-57040: Corrected the context constraints for the questionnaire-minOccurs and questionnaire-maxOccurs extensions
FHIR-50924: The hl7-work-group code system and value set in this package are withdrawn and replaced by the HL7 International Organizational Entities code system and value set in HL7 Terminology (THO)
The largeValue extension has a constraint (lv-1) that the value is a whole number
The value of the entered-in-error-status extension is a string (was url). A code is also allowed but is deprecated: it is provided only because all existing versions of FHIR erroneously use a code, and future versions will use string
Fixed the missing sub-extension urls for the quantity-confidenceInterval extension
Corrected the FHIRPath constraint on the questionnaire-choiceOrientation extension, and added test cases for it and for largeValue
Version ranges (version-specific-use) added or corrected for the contexts of artifact-copyrightLabel, consent-provision-expression and consent-provision-limit, and for the bases of the workflow-EpisodeOfCare search parameter
The value-filter-comparator value set is no longer defined in this package
Corrected the cardinality of the authorization-hint extension, the status of a number of code systems, value sets and extensions, and duplicate OIDs (see the table below)
FHIR-54534: New extension attachment-hostingEndpoint - the Endpoint that hosts the content referenced by the url of an Attachment
FHIR-56413: Aligned the definitions of the obligation-profile-flag and inherit-obligations extensions: obligation profiles can add non-conformance strength additional bindings and obligations (not cardinality changes), and both are what is inherited
FHIR-58947: New extension request-category - partitions a RequestOrchestration (RequestGroup in R4/R4B) into categories for searching, access control and system behavior
FHIR-59245: New extension request-performer - the specific performer (or non-performer) of a RequestOrchestration (RequestGroup in R4/R4B)
FHIR-59243: New extension request-location - the location at which a RequestOrchestration (RequestGroup in R4/R4B) should be performed
FHIR-59244: New extension request-occurrence - when the service requested by a RequestOrchestration (RequestGroup in R4/R4B) should occur
FHIR-52885: New extension cqf-applicabilityBehavior (with code system and value set action-applicability-behavior) - whether child actions are evaluated independently (all) or in order with the first applicable one performed (any), for pre-adoption of the R6 element. The cqf-qualityOfEvidence, cqf-strengthOfRecommendation, targetConstraint, timing-daysOfCycle and variable extensions can also be used on nested actions and items (PlanDefinition.action.action, RequestGroup/RequestOrchestration.action.action, Questionnaire.item.item)
FHIR-54631: The consent-provision-limit extension can also be used on nested provisions (Consent.provision.provision)
FHIR-53022 and FHIR-52986: The binding on the observation-structureLaterality extension is now extensible (was required) and the extension is limited to R5 and earlier; the ServiceRequest context of procedure-targetBodyStructure is limited to R4B and earlier (R5 ServiceRequest has bodyStructure), with a note that it is not needed for Procedure in R6
The dosage-minimumGapBetweenDose extension is corrected to a simple Duration value - it was erroneously published with the content of the dosage-conditions extension
