Definitions for the codexrt-radiotherapy-fractions-planned extension.
Guidance on how to interpret the contents of this table can be found here.
| 1. Extension | |
| Definition | The number of planned fractions in this scope. This extension SHALL only be present if the treatment is structured as countable fractions, for example in a Radiotherapy Planned Phase or in a Radiotherapy Treatment Plan. Optional Extension Element - found in all resources. |
| Control | 0..1* |
| 2. Extension.extension | |
| Control | 0..0* |
| 3. Extension.url | |
| Fixed Value | http://hl7.org/fhir/us/codex-radiation-therapy/StructureDefinition/codexrt-radiotherapy-fractions-planned |
| 4. Extension.value[x] | |
| Control | 10..1 |
| Type | Choice of: , date, Meta, Address, Attachment, integer, Count, DataRequirement, Dosage, uuid, Identifier, Coding, SampledData, id, Distance, Period, Duration, canonical, Range, RelatedArtifact, base64Binary, UsageContext, Timing, decimal, CodeableConcept, ParameterDefinition, dateTime, code, string, Contributor, oid, instant, ContactPoint, HumanName, Money, markdown, Ratio, Age, Reference, TriggerDefinition, Quantity, uri, url, Annotation, ContactDetail, boolean, Expression, Signature, unsignedInt, time |
| [x] Note | See Choice of Data Types for further information about how to use [x] |
| Primitive Value | This primitive element may be present, or absent, or replaced by an extension |

| 1. Extension | |
| Definition | The number of planned fractions in this scope. This extension SHALL only be present if the treatment is structured as countable fractions, for example in a Radiotherapy Planned Phase or in a Radiotherapy Treatment Plan. Optional Extension Element - found in all resources. |
| Control | 0..1* This element is affected by the following invariants: ele-1 |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |
| 2. Extension.extension | |
| Definition | An Extension 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..0* |
| Type | Extension |
| Summary | false |
| 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. |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |
| Slicing | This element introduces a set of slices on Extension.extension. The slices are unordered and Open, and can be differentiated using the following discriminators:
|
| 3. Extension.url | |
| Definition | Source of the definition for the extension code - a logical name or a URL. |
| Control | 1..1 |
| Type | uri |
| XML Representation | In the XML format, this property is represented as an attribute. |
| Summary | false |
| 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/us/codex-radiation-therapy/StructureDefinition/codexrt-radiotherapy-fractions-planned |
| 4. Extension.value[x] | |
| Definition | Value of extension - must be one of a constrained set of the data types (see Extensibility for a list). |
| Control | 10..1 |
| Type | Choice of: positiveInt, date, Meta, Address, Attachment, integer, Count, DataRequirement, Dosage, uuid, Identifier, Coding, SampledData, id, Distance, Period, Duration, canonical, Range, RelatedArtifact, base64Binary, UsageContext, Timing, decimal, CodeableConcept, ParameterDefinition, dateTime, code, string, Contributor, oid, instant, ContactPoint, HumanName, Money, markdown, Ratio, Age, Reference, TriggerDefinition, Quantity, uri, url, Annotation, ContactDetail, boolean, Expression, Signature, unsignedInt, time |
