This extension asserts that the data in a resource was authored (collected/handled/created/transformed) by an application that claims conformance to the definition of a feature. Note that 'authoring' is often a client function, but that is not always the case. For further information about features, see the [Application Feature Framework Implementation Guide](https://build.fhir.org/ig/HL7/capstmt/specification.html). As an example of the kind of use this extension might support, an application could choose to only use value set expansions that are explicitly labeled as 'prepared under the conformance rules defined in the [CRMI implementation guide](https://build.fhir.org/ig/HL7/crmi-ig). This extension is a statement about the provenance of a resource and is placed in the resource about which the assertion is made. The assertion SHOULD be removed when the resource data is altered (it may be replaced by a new assertion). See the related extension for [declaring feature conformance in the Provenance](StructureDefinition-target-feature-assertion.html)'. This assertion is often used to drive processing rules associated with the trustworthiness of the data in the resource. Applications/specifications/workflows that make use of this assertion should carefully consider the integrity of the chain of handling from the source the processing before choosing to trust the assertion. A more complex alternative to this profile is to use the [http://hl7.org/fhir/StructureDefinition/obligations-profile] extension.
Authored by an application conforming to a set of obligations
A declaration that the data in a resource was authored by an application that conformed to the set of element level obligations described in the referenced profile
This extension is a statement about the provenance of a particular version of the resource that it is describing; as such, it should be made in a Provenance resource referring to that particular version. Alternatively, the extension can be placed in the resource about which the declaration is made (in Resource.meta); in this case, the declaration SHOULD be removed when the resource data is altered (it may be replaced by a new declaration).
All FHIR elements must have a @value or children
hasValue() or (children().count() > id.count())
Must have either extensions or value[x], not both
Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Extensions are always sliced by (at least) url
Additional content defined by implementations
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.
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.
A reference to the definition of the feature by its canonical URL
The type is `uri` not `canonical` because FeatureDefinition isn't a defined resource
Source of the definition for the extension code - a logical name or a URL.
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.
Value of extension - must be one of a constrained set of the data types (see [Extensibility](http://hl7.org/fhir/R5/extensibility.html) for a list).
The value of the feature (as defined in the definition of the feature)
Provides a value for a qualifier of the feature
A reference to the qualifier of the feature by its name
The value of the feature qualifier (as defined in the definition of the feature)
