       Provenance assertions are a form of contextual metadata and can themselves become important
       records with their own provenance. Provenance statement indicates clinical significance
       in terms of confidence in authenticity, reliability, and trustworthiness, integrity, and
       stage in lifecycle (e.g. Document Completion - has the artifact been legally authenticated),
