Issue
Currently there is no way include a digital signature in the document header along with the identity of an author, authenticator, or legal authenticator. This information is often mandatory for legally binding documents.
Severity:High
High: The workaround "Signature" section (see Dicussion) is inefficient and duplicative of metadata specified in the HL7 RIM (Participation.signatureText). CBCC WG Wiki
Recommendation
- Add "signatureText" attribute to Participation occurrences in the document header.
Rationale
Needed for Consent Directive representations. The current workaround is to specify a "Signature" section in structure body of a document:
<section classCode="DOCSECT" moodCode="EVN">
<title>Signatures</title>
<text> This section contains the signatures of the relevant
authenticators</text>
<entry typeCode="COMP">
<observationMedia classCode="OBS" moodCode="EVN">
<value mediaType="application/pdf" representation="B64">
...
</value>
</observationMedia>
</entry>
</section>
This method, however, does not specify how to which authenticator is belongs, the narrative block has to specify using references.
