Detailed Descriptions for the elements in the extension.
Extension | |||||||||||||
Element Id | Extension | ||||||||||||
Definition | Days of a possibly repeating cycle on which the action is to be performed. The cycle is defined by the first action with a timing element that is a parent of the daysOfCycle. | ||||||||||||
Control | 1..1 This element is affected by the following invariants: ele-1 | ||||||||||||
Comments | The cycle is defined by a parent/containing action, and the daysOfCycle extension is used on individual actions within that cycle to indicate the days of the cycle on which the actions should be performed. | ||||||||||||
Invariants |
| ||||||||||||
Extension.id | |||||||||||||
Element Id | Extension.id | ||||||||||||
Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. | ||||||||||||
Control | 0..1 | ||||||||||||
Type | string | ||||||||||||
Extension.extension | |||||||||||||
Element Id | Extension.extension | ||||||||||||
Definition | 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. | ||||||||||||
Control | 0..* | ||||||||||||
Type | Extension | ||||||||||||
Alternate Names | extensions, user content | ||||||||||||
Comments | 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. | ||||||||||||
Slicing | This element introduces a set of slices. The slicing rules are:
| ||||||||||||
Extension.extension(day) | |||||||||||||
Element Id | Extension.extension:day | ||||||||||||
Definition | An integer that specifies a day on which the action is to be performed (starting at one). In most cases, the first day of the first cycle will be day 1. | ||||||||||||
Control | 1..* | ||||||||||||
Type | Extension | ||||||||||||
Extension.extension.id | |||||||||||||
Element Id | Extension.extension:day.id | ||||||||||||
Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. | ||||||||||||
Control | 0..1 | ||||||||||||
Type | string | ||||||||||||
Extension.extension.extension | |||||||||||||
Element Id | Extension.extension:day.extension | ||||||||||||
Definition | An Extension | ||||||||||||
Control | 0..0 | ||||||||||||
Type | Extension | ||||||||||||
Slicing | This element introduces a set of slices. The slicing rules are:
| ||||||||||||
Extension.extension.url | |||||||||||||
Element Id | Extension.extension:day.url | ||||||||||||
Definition | Source of the definition for the extension code - a logical name or a URL. | ||||||||||||
Control | 1..1 | ||||||||||||
Type | uri | ||||||||||||
Comments | 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. | ||||||||||||
Fixed Value | day | ||||||||||||
Extension.extension.valueInteger | |||||||||||||
Element Id | Extension.extension:day.valueInteger | ||||||||||||
Definition | Value of extension - may be a resource or one of a constrained set of the data types (see Extensibility in the spec for list). | ||||||||||||
Control | 0..1 | ||||||||||||
Type | integer | ||||||||||||
Extension.url | |||||||||||||
Element Id | Extension.url | ||||||||||||
Definition | Source of the definition for the extension code - a logical name or a URL. | ||||||||||||
Control | 1..1 | ||||||||||||
Type | uri | ||||||||||||
Comments | 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. | ||||||||||||
Fixed Value | http://hl7.org/fhir/StructureDefinition/timing-daysOfCycle | ||||||||||||
Extension.value[x] | |||||||||||||
Element Id | Extension.value[x] | ||||||||||||
Definition | Value of extension - may be a resource or one of a constrained set of the data types (see Extensibility in the spec for list). | ||||||||||||
Control | 0..0 | ||||||||||||
Type | Choice of: base64Binary, boolean, canonical, code, date, dateTime, decimal, id, instant, integer, markdown, oid, positiveInt, string, time, unsignedInt, uri, url, uuid, Address, Age, Annotation, Attachment, CodeableConcept, Coding, ContactPoint, Count, Distance, Duration, HumanName, Identifier, Money, Period, Quantity, Range, Ratio, Reference, SampledData, Signature, Timing, ParameterDefinition, DataRequirement, RelatedArtifact, ContactDetail, Contributor, TriggerDefinition, Expression, UsageContext, Dosage | ||||||||||||
