Detailed Descriptions for the elements in the extension.
Extension | |||||||||||||
Element Id | Extension | ||||||||||||
Definition | Specifies that a date is relative to some event. The event happens [Duration] after [Event]. | ||||||||||||
Short Display | Relative Date Criteria | ||||||||||||
Cardinality | 0..1 | ||||||||||||
Comments | This extension is used when a precise date is not known, but rather, the date will be relative to some future event (e.g. Do this 2 weeks after an operation). | ||||||||||||
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. | ||||||||||||
Short Display | Unique id for inter-element referencing | ||||||||||||
Cardinality | 0..1 | ||||||||||||
Type | id | ||||||||||||
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. | ||||||||||||
Short Display | Additional content defined by implementations | ||||||||||||
Cardinality | 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:
| ||||||||||||

Cardinality | 0..1 | ||||||||||||
Type | Extension | ||||||||||||
Comments | The specified path SHALL be a FHIRPath resolveable on the specified type of the DataRequirement, and SHALL consist only of identifiers, constant indexers, and .resolve(). The path is allowed to contain qualifiers (.) to traverse sub-elements, as well as indexers ([x]) to traverse multiple-cardinality sub-elements (see the Simple FHIRPath Profile for full details). Note that the index must be an integer constant. The path must resolve to an element of type date, dateTime, Period, Schedule, or Timing. | ||||||||||||
