Definitions for the event-time-only extension.
See the documentation on how to interpret the contents of this table
| 0. Extension | |
| Definition | 只用於 dateTime 型別元素；choice 元素只用 dateTime 分支，Period 用於 start 與 end。兩種用法：一、來源只有時間、沒有日期：原元素不填值，只在該元素的 extension 放入本 Extension，例如 Procedure._performedDateTime；此用法不適用 Observation.effective[x]，評估時間缺日期時改存登錄表單。二、來源有日期與時間但時區尚未確認：原元素只填日期（YYYY-MM-DD），並在該元素的 extension 放入本 Extension 保留來源時鐘時間。 Optional Extension Element - found in all resources. |
| Short | 來源事件時間（無日期、無時區）Optional Extensions Element |
| Control | 0..* This element is affected by the following invariants: ele-1 |
| Is Modifier | false |
| Invariants | 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())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. |
| Short | ExtensionAdditional content defined by implementations |
| 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. |
