| 1 | | Conceptmap | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | This extension references a ConceptMap that maps to relevant terminologies used in an implementation. |
| 2 | | Conceptmap | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | This extension references a ConceptMap that maps to relevant terminologies used in an implementation. |
| 3 | | Extension Style Extension | hl7.fhir.uv.tools#current | R5 | How the type can be extended. Note that all FHIR types that inherit from ```Element``` have extension-style = fhir-extensions |
| 4 | | Inherit Obligations | hl7.fhir.uv.tools#current | R5 | Inherit all the obligations from an Obligation Profile |
| 5 | | Logical Target | hl7.fhir.uv.tools#current | R5 | This extension is used logical models to indicate that this type can be the target of a reference. This indicates that there is a persistence identity and maintenance lifecycle for the type, though there are no requirements for how those are defined. |
| 6 | | ModelInfo Is Included | hl7.fhir.uv.crmi#current | R4 | Specifies whether the profile should be included in the model info constructed for an artifact collection such as an implementation guide. If this extension is not present, included is true by default for resources and profiles, but not data types (unless they are indirectly referenced by included resources or profiles). Note that even if isIncluded is false for a resource or profile, it will still be included in model info if it is a required dependency of some other included resource, profile, or data type. |
| 7 | | ModelInfo Is Retrievable | hl7.fhir.uv.crmi#current | R4 | Specifies whether the class constructed for the profile should be marked as retrievable in the model info (meaning whether or not it can appear as the target of a retrieve expression). If this value is not specified, retrievable is true for resources and false for data types. |
| 8 | | ModelInfo Label | hl7.fhir.uv.crmi#current | R4 | Specifies the label for the class constructed in the model info for the profile (i.e. an alternative, user-friendly name that can be used as the identifier for the class in CQL expressions). |
| 9 | | ModelInfo Primary Code Path | hl7.fhir.uv.crmi#current | R4 | Specifies the primary code path for the class constructed in the model info for the profile (i.e. the path to the code-valued element on the resource that should be used as the default terminology filter when no terminology target is specified in a CQL retrieve). |
| 10 | | Namespace | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | Use this extension to indicate tha the element has an XML namespace different to http://hl7.org/fhir. The special value `noNamespace` indicates that there is no assigned XML namespace. |
| 11 | | Obligation Extension | hl7.fhir.uv.tools#current | R5 | This definition is deprecated in favor of the same extension in the core extensions pack. Documents obligations that apply to applications implementing this element. The obligations relate to application behaviour, not the content of the element itself in the resource instances that contain this element. See [Obligation Extension](obligations.html) for further detail. |
| 12 | | Obligation Profile Flag | hl7.fhir.uv.tools#current | R5 | Profiles marked to be 'Obligation Profiles' cannot introduce new structural elements or slicing, but they can add additional bindings, and additional obligations on the elements that are already defined |
| 13 | | Permitted Value Conceptmap | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | Expresses the linkage between the internal codes used for storage and the codes used for exchange. |
| 14 | | Permitted Value Conceptmap | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | Expresses the linkage between the internal codes used for storage and the codes used for exchange. |
| 15 | | Permitted Value Valueset | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | Allows expressing the value set that must be stored internally by the system (as distinct from the base value set which defines values for exchange). |
| 16 | | Permitted Value Valueset | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | Allows expressing the value set that must be stored internally by the system (as distinct from the base value set which defines values for exchange). |
| 17 | | Replaces | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | This indicates a separate conformance resource instance that is superseded by the current instance. |
| 18 | | Resource Approval Date | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | The date on which the asset content was approved by the publisher. Approval happens once when the content is officially approved for usage. |
| 19 | | Resource Effective Period | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | The period during which the resource content was or is planned to be effective. |
| 20 | | Resource Last Review Date | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | The date on which the asset content was last reviewed. Review happens periodically after that, but doesn't change the original approval date. |
| 21 | | Structure Definition Summary | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | Additional text for the summary presentation. |
| 22 | | Structure Type Characterstics (Constraint Control) | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | A code that indicates that a particular type characteristic and it's associated element definition aspects apply to this type |
| 23 | | StructureDefinition Ancestor | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | A canonical reference to a StructureDefinition that this is derived from. This is a de-normalization of a chain of StructureDefinition.baseDefinition. |
| 24 | | StructureDefinition Applicable Version | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | An additional version that this profile apples to, other than the version explicitly stated in StructureDefinition.fhirVersion. |
| 25 | | StructureDefinition Category | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | The category under which the resource type is presented on the official resource list. |
| 26 | | StructureDefinition Codegen Super | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | A specific instruction to use an intermediate parent class when generating code for the classes. |
| 27 | | StructureDefinition Compiles With Profile | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | Asserts that instances that are valid against this profile are also automatically valid against the StructureDefinition referenced by this extension. |
| 28 | | StructureDefinition Dependent Profiles | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | Instances can only be valid against this profile, if they also successfully validate against the profile referenced by this extension. |
| 29 | | StructureDefinition FMM If No Warnings | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | The FMM level that would be assigned to the artifact if it had no warnings. |

| 31 | | StructureDefinition Interface | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | Marks that the resource definition represents an [interface](uml.html#interface) rather than a resource. |
| 32 | | StructureDefinition Security Category | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | Provides general guidance around the kind of access Control to Read, Search, Create, Update, or Delete the resource. |
