Structure of the consent document. The consent document is based on HL7 version 3 CDA. The header contains meta data about the patient (e.g. MPI-ID), the author and the legal authenticator. The body displays information like the involved providers and organizations as well as the consent information itself as assembled by the patient. The consent content (which person or organization is allowed to perform which transactions on which documents) is represented in an XACML policy set inside the body structure of the CDA document as well as in a PDF representation and can optionally have a digital or wet signature.
