      v: 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).

      v: Additional content defined by implementations
    definition:
      v: 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 managable, 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.
    comment:
      v: 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.

comment:
  v: The specified path SHALL be a FHIRPath resolveable on the specified type of the DataRequirement. The path must resolve to an element of type date, dateTime, Period, Schedule, or Timing. The `reference` plus the `targetPath` provides a fully computable anchor (e.g. `Patient.birthDate` or `ResearchSubject.progress.where(milestone.coding.where(system=x and code=y).exists()).startDate)`, while `targetCode` gives something that is more meaningful to a user (e.g. 'age', 'startOfTreatment'). Often there might be utility in having both.

  comment:
    v: The specified path SHALL be a FHIRPath resolveable on the specified type of the DataRequirement. The path must resolve to an element of type date, dateTime, Period, Schedule, or Timing. The `reference` plus the `targetPath` provides a fully computable anchor (e.g. `Patient.birthDate` or `ResearchSubject.progress.where(milestone.coding.where(system=x and code=y).exists()).startDate)`, while `targetCode` gives something that is more meaningful to a user (e.g. 'age', 'startOfTreatment'). Often there might be utility in having both.

  v: Duration before or after the event
definition:
  v: The duration before or after the event that the element on which this extension appears is asserted to be.
comment:
  v: a negative offset indicates a duration 'prior' to the event. E.g. "3 days prior to patient death". A positive offset indicates a duration 'after' the event. E.g. "27 years after birth - i.e. Age 27". An offset of 0 indicates occurrence simultaneous with the referenced event. E.g. "Started therapy immediately on admission".
