Cross-version Extension for R5.EvidenceVariable.characteristic.timeFromEvent for use in FHIR R4
This cross-version extension represents EvidenceVariable.characteristic.timeFromEvent from http://hl7.org/fhir/StructureDefinition/EvidenceVariable|5.0.0 for use in FHIR R4.
Timing in which the characteristic is determined
All FHIR elements must have a @value or children
hasValue() or (children().count() > id.count())
Must have either extensions or value[x], not both
exists(f:extension)!=exists(f:*[starts-with(local-name(.), 'value')])
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
exists(f:extension)!=exists(f:*[starts-with(local-name(.), "value")])
This cross-version extension represents EvidenceVariable.characteristic.timeFromEvent.description from http://hl7.org/fhir/StructureDefinition/EvidenceVariable|5.0.0 for use in FHIR R4.
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 manageable, 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.
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.
A human-readable string to clarify or explain concepts about the timeFromEvent.
The event used as a base point (reference point) in time
This cross-version extension represents EvidenceVariable.characteristic.timeFromEvent.event[x] from http://hl7.org/fhir/StructureDefinition/EvidenceVariable|5.0.0 for use in FHIR R4.
Used to express the observation at a defined amount of time before or after the event
This cross-version extension represents EvidenceVariable.characteristic.timeFromEvent.quantity from http://hl7.org/fhir/StructureDefinition/EvidenceVariable|5.0.0 for use in FHIR R4.
Used to express the observation within a period before and/or after the event
This cross-version extension represents EvidenceVariable.characteristic.timeFromEvent.range from http://hl7.org/fhir/StructureDefinition/EvidenceVariable|5.0.0 for use in FHIR R4.
Value of extension - must be one of a constrained set of the data types (see [Extensibility](http://hl7.org/fhir/R4/extensibility.html) for a list).
