description: This Bundle profile enforces the various elements of signature documented in the CDex guide. It adds the following *mandatory* (min=1) constraints:\n\n- A Bundle.signature element representing the enveloped signature\n- A Bundle.signature.type fixed to ASTM Standard, E1762-95(2013) code = “1.2.840.10065.1.12.1.5” (Verification Signature)\n- A Bundle.signature.who for the organization or practitioner who signed the Bundle which is either:\n  1. a reference to US-Core Practitioner, PractitionerRole or Organization or\n  1. an NPI or Tax ID and name of the organization or practitioner\n- A Bundle.signature.data representing base64 encoded JWS-Signature \n\nIn addition, the following *mandatory* (min=1) element is inherited from the base standard:\n- Bundle.signature.when - system timestamp when the signature was created
