  <description value="The AdvanceDirective concept of zib TreatmentDirective." />
  <purpose value="This extension represents the AdvanceDirective concept of the Dutch [zib ('Zorginformatiebouwsteen', i.e. Health and Care Information Model) TreatmentDirective2-v1.0(2020EN)](https://zibs.nl/wiki/TreatmentDirective2-v1.0(2020EN)). The cardinality of the `Consent.source[x]` element does not comply with the cardinality of the AdvanceDirective concept (NL-CM:2.2.8). This is solved by adding an extension that can be used to provide additional sources after the `Concent.source[x]` is populated first." />
